Membranes for optically sensing Ag+ and Hg2+ based on plasticized poly(vinyl chloride) (PVC) containing a metal ion-selective ionophore, a hydrogen ion-selective chromoionophore, and lipophilic anionic sites are presented. Different dithiocarbamate ionophores have been used to develop novel optical sensors for environmental analysis. Optode membranes based on the ionophore methylene bis(diisobutyldithiocarbamate) (MBDiBDTC) reversibly respond to Ag+ and Hg2+ and show extremely high selectivities over Li+, Na+, K+, Mg2+, Cu2+, Cd2+, and Pb2+. The detection limit for Ag+ is 2.5 × 10-9 M at pH 4.7. The dynamic range, response behavior, reversibility, and selectivity of the optode membranes are discussed.

The synthesis of sulphur and nitrogen containing dithiocarbamato ligand derived from diisobutylamine as well as its coordination compounds with 3d series transition metals is presented. These synthesized compounds were characterized on the basis of elemental analysis, conductometric measurements and IR spectral studies. The analytical data showed the stoichiometry 1:2 and 1:3 for the compounds of the types ML2 {M=Mn(II), Co(II), Ni(II), Cu(II) and Zn(II)} and M'L3{M'=Cr(III) and Fe(III)} respectively. The conductometric measurements proved the non-electrolytic behaviour of all the compounds. The bidentate nature of dithiocarbamato moiety was confirmed on the basis of IR spectral data.

A pyridine adduct of bis(di-iso-butyldithiocarbamato-S,S′)cadmium(II) : Multinuclear (13C, 15N, 113Cd) CP/MAS NMR spectroscopy, crystal and molecular structure, and thermal behaviour

Crystalline bis(N,N-di-iso-butyldithiocarbamato-S,S′)(pyridine) cadmium(II) - adduct 1 was prepared and studied by means of multinuclear 13C, 15N, 113Cd CP/MAS NMR spectroscopy, single-crystal X-ray diffraction and simultaneous thermal analysis (STA). In molecular structure 1, the cadmium atom coordinates with four sulphur atoms and one nitrogen atom of pyridine, forming a coordination polyhedron [CdS 4N], whose geometry is an almost ideal tetragonal pyramidal (C 4v). The coordinated py molecule is in the apical position, while two structurally non-equivalent di-iso-butyldithiocarbamate ligands, playing the same terminal S,S′-chelating function, define the basal plane. To characterise additionally the structural state of the cadmium atom in this fivefold coordination, 113Cd chemical shift anisotropy (CSA) parameters, δaniso and η, were calculated from experimental MAS NMR spectra that revealed an almost axially symmetric 113Cd chemical shift tensor. From a combination of TG and DSC measurements taken under an argon atmosphere, we found that the mass of adduct 1 is lost in two steps involving initial desorption of coordinated py molecules with subsequent thermal destruction of liberated cadmium(II) di-iso-butyldithiocarbamate, with yellow-orange, fine-powdered solid CdS as the final product.
Gold(III)-iron(III) heteropolynuclear complexes ([Au{S2CNR2}2][FeCl4]) n (R = C4H9, iso-C4H9): Chemisorption synthesis, supramolecular self-organization, and thermal behavior

The reactions of iron(III) dibutyl and di-iso-butyl dithiocarbamates [Fe(S2CNR2)3] (R = C4H9, iso-C4H9) with anions [AuCl4]- in 2 M HCl are studied. The result of heterogeneous reactions of gold(III) chemisorption binding from a solution is the formation of gold(III)-iron(III) heteropolynuclear complexes of the ionic type. The crystal and supramolecular structures of polymer complexes ([Au{S2CN(C4H9)2}2][FeCl4]) n (I) and ([Au{S2CN(iso-C4H9)2}2][FeCl4]) n (II) are determined by X-ray diffraction analysis (CIF files CCDC 1407704 (I) and 1407802 (II)). The structure of complex I contains two centrosymmetrical structurally nonequivalent complex cations [AuS{2CN(C4H9)2}2]+ (A and B) and complex anion [FeCl4]-. Structure II is formed by three isomeric complex cations [Au{S2CN(iso-C4H9)2}2]+ (A, B, and C) and two anions [FeCl4]- related as conformers. The isomeric cations are involved in the formation of linear (?A?B?) n (in I) or zigzag (?A?B?A...C...) n (in II) polymer chains due to pairs of weak secondary interactions Au?S. The thermal behavior of the complexes is studied by simultaneous thermal analysis. Thermal destruction includes the thermolysis of the dithiocarbamate moiety of the complexes and anions [FeCl4]- with the reduction of gold(III), release of FeCl3, and partial formation of Fe2O3. The final thermolysis products are metallic gold and Fe2O3.
