Usage

General Description

DICHLORO(N,N,N',N'-TETRAMETHYLETHYLENEDIAMINE)ZINC, also known as zinc dichloride, is a chemical compound with the formula ZnCl2. It is a coordination complex formed by the coordination of two chloride ions to a central zinc atom, and the chelation of a tetramethylethylenediamine ligand to the zinc ion. DICHLORO(N,N,N',N'-TETRAMETHYLETHYLENEDIAMINE)ZINC is used in various industrial processes, including as a catalyst in organic synthesis reactions and as a dehydrating agent in organic chemical reactions. It is a white, crystalline solid with a melting point of 283°C, and is soluble in water, alcohol, and acetone. Additionally, it is an irritant to the skin, eyes, and respiratory system, and should be handled with care.

Synthesis and characterization of highly conductive charge-transfer complexes using positron annihilation spectroscopy

Molecular charge-transfer complexes of the tetramethylethylenediamine (TMEDA) with picric acid (Pi-OH), benzene-1,4-diol (QL), tin(IV) tetrachloride (SnCl4), iodine, bromine, and zinc chloride (ZnCl2) have been synthesized and investigated by elemental and thermal analysis, electronic, infrared, Raman and proton-NMR, energy-dispersive X-ray spectroscopy, X-ray powder diffraction and positron annihilation lifetime spectroscopy, and scanning electron microscopy. In this work, three types of acceptors π-acceptors (Pi-OH and QL), σ-acceptors (iodine and bromine), and vacant orbital acceptors (SnCl4 and ZnCl2) were covered. The results of elemental analysis indicated that the CT complexes were formed with ratios 1:1 and 1:2 for QL, SnCl4, and ZnCl2 acceptors and iodine, Pi-OH, and Br2 acceptors, respectively. The type of chelating between the TMEDA donor and the mentioned acceptors depends upon the behavior of both items. The positron annihilation lifetime parameters were found to be dependent on the structure, electronic configuration, and the power of acceptors. The correlation between these parameters and the molecular weight and biological activities of studied complexes was also observed. Regarding the electrical properties, the AC conductivity and the dielectric coefficients were measured as a function of frequency at room temperature. The TMEDA charge-transfer complexes were screened against antibacterial (Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa) and antifungal (Aspergillus flavus and Candida albicans) activities.

Structural Characterization and Unique Catalytic Performance of Silyl-Group-Substituted Geminal Dichromiomethane Complexes Stabilized with a Diamine Ligand

Stabilization by a silyl group on the methylene carbon and a diamine ligand led to the isolation of gem-dichromiomethane species. X-ray crystallography confirmed the identity of the structure of this rare example of reactive gem-dimetalloalkane species. T

A new allotrope of elemental sulfur: Convenient preparation of cyclo-S14 from S8

Three simple steps lead from S8 to cyclo-S14, which is stable at 20°C. The final synthetic step [Eq. (a)] provides the title compound, which was characterized spectroscopically and by X-ray structure analysis. Formally, the structure of S14 is derived by insertion of an S2 unit into S12. tmeda = N,N,N',N'-tetramethylethyl-enediamine.
