Abstract
New Hofmann type complexes in the form of M(CyHEA) 2Ni(CN) 4 (where CyHEA = 2-(1-cyclohexenyl)ethylamine; M = Ni or Co) have been prepared in powder form and their infrared spectra have been reported in the range of 4000–400 cm −1. The thermal behaviour of these complexes has been investigated by differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA). The results suggest that these compounds are similar in structure to Hofmann type complexes and their structures consist of polymeric layers |M–Ni(CN) 4| ∞ with the CyHEA molecule bound to the metal atom (M).
