Radical-based epoxide opening by titanocenes

The binding of 2,2-diphenyloxirane to Cp2TiCl is studied on the electronic level by magnetic resonance spectroscopy and quantum chemical calculations. The complexation of 2,2-diphenyloxirane is accompanied by dissociation of the chloride ligand, and thus, the epoxide binds to the cationic titanocene(III) complex. The titanocene(III)-epoxide species persists only for short periods of time (A short-lived paramagnetic titanocene(IV)-epoxide radical species has not been directly observed. However, by a combination of isotope labeling and spin-trapping, evidence for the existence of such a species has been unequivocally demonstrated. The observation of a titanocene(III)-epoxide complex is unprecedented and provides direct evidence for inner-sphere electron transfer between epoxides and titanocenes, responsible for the high regioselectivity of ring-opening.

Cu2ZnSnS4crystal growth using an SnCl2based flux

The stoichiometry and phase homogeneity of the kesterite type compound Cu2ZnSnS4play a key role in its efficiency in solar cells. In this work, CuCl2, ZnCl2and SnCl2were applied as solvents in the Cu2ZnSnS4crystal growth for the first time. The multiphase ingot was obtained by direct fusion of the stoichiometric batch composed of constituent elements. Compared to that, the material recrystallized in SnCl2presented a single-phase Zn-rich kesterite with composition Cu1.94Zn1.06SnS4and unit cell parameters ofa= 5.4324(3) andc= 10.8383(2) ?. The crystal structure of Cu1.94Zn1.06SnS4was determined by single crystal X-ray diffraction analysis. The integral phase purity of the crystals grown with the use of the SnCl2solvent was verified by powder X-ray diffraction analysis and Raman measurements. In the Raman spectrum, the FWHM value of the 337 cm?1line was as low as 9.6 cm?1that indicates the minimal lattice disorder.

Complexation of 2-hydroxynicotinic and 3-hydroxypicolinic acids with zinc(II). Solution state study and crystal structure of trans-diaqua-bis-(3- hydroxypicolinato)zinc(II)

The interactions between zinc(II) and the two ligands 2-hydroxynicotinic acid (HNic) and 3-hydroxypicolinic acid (HPic) have been investigated by means of potentiometric titrations in aqueous 0.6 m (Na)Cl at 25 °C. In both cases, only mononuclear complexes are formed. The qualitative and quantitative results obtained have been confirmed in part by UV-Vis spectrophotometry and 1H NMR spectroscopy. The complex trans-diaqua-bis-(3- hydroxypicolinato)zinc(II) was obtained as a crystal and examined by X-ray crystallography. The thermodynamic results allow drawing some conclusions regarding the extent of Zn(II) interference in a hypothetical chelation therapy treatment of aluminium or iron overload with these two ligands.

COORDINATION OF 3-SUBSTITUTED 1-AZA-4-OXO-1,3-BUTADIENES (α-IMINOESTERS AND AMIDES) TO ALUMINUM AND ZINC CHLORIDE AND TO DIMETHYLZINC. SELECTIVE REDUCTION IN THE ZnEt2-R1N=CHC(NEt2)=O SYSTEM, AND CRYSTAL STRUCTURE OF 2

Reactions of ZnCl2 and AlCl3 with 3-substituted 1-aza-4-oxo-1,3-butadienes (α-iminoesters and amides) have given the corresponding 1:1 complexes MCl(n)3)=O> (R3 = OMe, OEt or NEt2).The α-iminoester and amide ligands in these complexes are chelate-bonded via the imino-N and carbonyl-O atoms, except for the AlCl3-α-iminoamide complex in which the α-iminoamide is monodentate-N coordinated.Stable 1:1 coordination complexes, ZnMe23)=O> (R3 = OMe, OEt or NEt2), have also been isolated from the reaction of ZnMe2 with these α-iminoesters and amides.The α-iminoesters are chelate bonded to the zinc centre via the imino-N and the alkoxy-O atoms, whereas the α-imino-amides are bonded via the imino-N and carbonyl-O atoms.Similar 1:1 complexes could not be isolated from the reaction of ZnEt2 with α-iminoamides.Instead, products formed by N-addition as well as by N=C reduction and C-C dimerization reactions were obtained.The occurrence of reduction in these reactions are demonstrated by an X-ray crystal structure determination of 2 (12).The crystals are monoclinic, with cell dimensions a 20.413(2), b 8.445(2), c 19.177(2) Angstroem and β 115.59(1) degree.The final R-value was 0.055 for 2222 reflexions.The dimeric molecule consists of a central four-membered Zn2N2 ring which links the two halves of the dimer.Coordination of the amide-O atom to zinc results in formation of a five-membered ZnOCCN ring and completes the four coordination at zinc.Comparison of the products formed in the reaction of ZnEt2 with various 1-aza-4-oxo(aza)-1.3-butadienes, i.e. α-iminoketones, α-iminoamides, 1,4-disubstituted 1,4-diaza-1,3-butadienes (R-DAB and pyridylcarbaldehyde imine (R-Pyca)) pointed to a striking mechanistic similarity of these reactions with respect to chelate coordination as the initial step, SET activation, single electron transfer, and inter-and intramolecular transfer of the organo group from zinc to the organic moiety.

Crystal growth, structure and characterizations of a new semiorganic nonlinear optical material-β-Alanine zinc chloride

The title compound, β-alanine zinc chloride-a new semiorganic nonlinear optical crystal was grown by slow evaporation technique. Single crystals of β-alanine zinc chloride have been subjected to X-ray diffraction analysis to determine the crystal structure. The powder X-ray diffractogram of the crystal has also been recorded. The amount of carbon, nitrogen and hydrogen in the crystals was also estimated. Fourier Transform Infrared and Raman spectral measurements have been carried out on the grown crystals in order to identify the functional groups. The presence of hydrogen and carbon in the β-alanine zinc chloride was confirmed by using proton and carbon nuclear magnetic resonance spectral analyses. The percentage of zinc in the crystal was determined by atomic absorption spectroscopy. Optical behavior such as ultraviolet-vis-near infrared transmittance spectrum and second harmonic generation has been investigated. The mechanical strength and thermal behavior of the grown crystal have been analyzed.

Synthetic, Spectroscopic and X-Ray Crystallographic Studies of Bivalent Metal Complexes with Amino Acids Having a Thiazolidine Ring. I. Properties of Bivalent Me Complexes with (S)-4-Thiazolidinecarboxylic Acid and the Structure of Chloro((S)-4-thiazolidine-carboxylato) ...

Complexes of five bivalent metals with (S)-4-thiazolidinecarboxylic acid (CH2-S-CH2-NH-CH-COOH) have been prepared by three methods and characterized by means of infrared absorption, reflection spectra, magnetic susceptibility, thermal analysis, powder X-ray patterns, and single crystal X-ray diffraction.Two types of complexes were found.The first type> included ML2-nH2O (M=Co(II), Ni(II), Cu(II), Zn(II), Cd(II); L=(S)-4-thiazolidinecarboxylate anion) and ZnClL(HL) was the second type.In A-type complexes, the ligand coordinates to the metal with a nitrogen atom and an oxygen atom.From the results of single-crystal X-ray diffraction studies, the second type-B ZnClL(HL) was found to be orthorhombic, with the space group P212121; a=9.719(2), b=22.194(4), c=5.8537(5) Angstroem, U=1262.6(4) Angstroem3, Z=4, Dm=1.91 Mg m-3, Dx=1.93 Mg m-3, and μ(MoKα)=25.3 cm-1.Block-diagonal least-squares refinements have led to a final R value of 0.045.The zinc atom is penta-coordinated, being ligated with one carboxylate oxygen atom of (S)-thiazolidinium-4-carboxylate, which has a zwitter ion structure, two carboxylato oxygeb atoms and one nitrogen atom of (S)-4-thiazolidinecarboxylate anion, and a chloride atom.The structure comprises one-dimensional polymers by the carboxylate oxygen atom of this anion-type ligand.The plane extends in the direction of c-axis.In neither the A- nor the B-type complexes does the ligand coordinate to a metal with a sulfur atom.

Immobilization of kojic acid in ZnAl-hydrotalcite like compounds

Kojic acid (KOJ) is a melanin synthesis inhibitor widely used as skin lightening agent in topical preparations. Unfortunately it is easily susceptible to photo-oxidation, phenomenon responsible for chemical and organoleptic modifications. The aim of this work was the intercalation of KOJ in hydrotalcite-like compounds (HTlc) in order to stabilize KOJ and to reduce its photolability. Hydrotalcite containing Zn and Al (ZnAl-HTlc) was used as host to obtain the final compound ZnAl-HTlc-KOJ. The intercalation was carried out, after many attempts, by ionic exchange mechanism by means of the strong base EtO- in anhydrous ethanol/dimethylsulfoxide (DMSO) mixture as solvent in order to generate KOJ- anions. The final product was characterized by the X-ray powder diffraction (XRPD), FT-IR spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and elemental analysis. The intercalated compound was formulated in a siliconic water free self-emulsifying ointment and the in vitro release profile was evaluated. All samples (intercalation compound and its formulation) were submitted also to spectrophotometric assays in order to evaluate the matrix protective effect towards ultraviolet rays.

DOUBLE GOLD(III)–ZINC(II) DI-ISO-BUTYLDITHIOCARBAMATO- CHLORIDO COMPLEXES OF THE COMPOSITION [Au(S2CNR2)2]2[Zn2Cl6] AND [Au(S2CNR2)2][Zn(S2CNR2)Cl2]: SYNTHESIS, STRUCTURAL ORGANIZATION, 13C CP-MAS NMR, AND THERMAL BEHAVIOR

Abstract: The interaction of zinc(II) di-iso-butyldithiocarbamate with [AuCl4]— anions in 2M HCl is studied. The result of chemisorption binding of gold(III) from a solution to the solid phase is the formation of double ionic complexes of the compositions [Au{S2CN(iso-C4H9)2}2]2[Zn2Cl6] (1) and [Au{S2CN(iso-C4H9)2}2][Zn{S2CN(iso-C4H9)2}Cl2] (2). The chemical identification of preparatively isolated crystalline compounds was performed by 13C CP-MAS NMR spectroscopy. According to single crystal X-ray diffraction data, structural units of complex 1 are a binuclear zinc anion and non-equivalent complex [Au{S2CN(iso-C4H9)2}2]+ cations: centrosymmetric A with the Au(1) atom and С – Au(3) and non-centrosymmetric В – Au(2). With the participation of secondary Cl?S bonds (3.2407?? and 3.2756??), В cations and anions form supramolecular ionic pairs. The structure of 2 in turn involves the centrosymmetric gold(III) cation whose counterion is a mixed-ligand dithiocarbamato-chlorido anion of zinc(II). Pairs of non-equivalent secondary Cl?S bonds (3.2337?? and 3.3151??) combine the ionic structural units of 2 into zigzag-like pseudo-polymeric chains along which the alternation of complex cations and anions is noted. Thermolysis of complexes in cationic and anionic parts is accompanied by the quantitative regeneration of bound gold along with the formation of ZnCl2 and ZnS.
