Abstract

Reaction of ZnCl2 and 2-thiophenecarboxylic hydrazide (tch), in ethanol resulted in the crystalline product [Zn(tch)3][ZnCl4] · 2EtOH, which slowly decomposes losing solvent molecules. The structure of the first compound has been determined by the single crystal X-ray method. Analysing the IR spectra of both compounds it has been found that the complex [Zn(tch)3]2+ cation and [ZnCl4]2− anion are preserved after crystal decomposition. Vibrational spectra of the obtained substances were interpreted with the assistance of DFT calculations and metal isotope as well as deuterium replacement.

Graphical abstractThe reaction of ZnCl2 with 2-thiophenecarboxylic hydrazide in ethanolic solution affords a salt with complexed metal present in the cation and anion. This compound has been characterized by single-crystal X-ray diffraction and by IR and Raman spectroscopy. The complex cation has a distorted octahedral environment around zinc(II) with a fac-orientation of the bidentate organic ligands. The cation is accompanied by a typical tetrachlorozincate(II) anion.Figure optionsDownload full-size imageDownload as PowerPoint slide
