A simple and safe method for the preparation of bis[2-(2H-tetrazol-5-yl)pyridinium] tetrachloridozincate(II)

Abstract

In the title complex salt, (C6H6N5)2[ZnCl4], the Zn(II) cation is coordinated by four chloride ligands in a distorted tetrahedral geometry. The organic cations and complex anions are connected by N-H···Cl hydrogen bonds, leading to the formation of a three-dimensional network. The title complex salt was synthesized by the reaction of sodium azide, pyridine-2-carbonitrile and ZnCl2 in aqueous solution. The salt was characterized by elemental analysis and IR and UV-Vis spectroscopy.
