FT-IR Spectroscopic and Some Thermal Properties of Hofmann-Type Clathrate and Transition Metal Complexes of 2-Aminothiazole

Abstract

In this study, new Hofmann type transition metal complexes of the form M(2-aminothiazole)₂Ni(CN)₄ (M = Mn, Fe, Co, Ni, Cu, Zn, Cd) and Cd(2-aminothiazole)₂Ni(CN)₄·C₆H₆, Hofmann type clathrate, have been prepared in powder form and their infrared spectra and some thermal decomposition properties of the clathrate are reported. The spectral and thermal data show that the structures of these complexes and the clathrate are analogous with related Hofmann type complexes. The observed n(C-N) wave numbers of the complexes are in good agrement with Irving-Williams natural stability series.
