FT-IR SPECTROSCOPIC INVESTIGATION OF SOME M(BENZOYL CHLORIDE)2Ni(CN)4 COMPLEXES (M = Co, Ni and Cd)
Abstract
New Hofmann-type complexes
formulated as M(Benzoyl chloride)2Ni(CN)4 (M = Co, Ni and Cd)
have been obtained in the
powder form and their FT-IR spectra have been reported in the range of
(4000-400) cm-1. The thermal behaviour of these complexes
has been also investigated by thermo-gravimetric analysis (TGA), differential
thermal analysis (DTA) and derivative thermal gravimetric analysis (DTG) in the
range of (30-700) oC. The spectral and thermal features
suggest that the compounds substantially isostructural to that of the already
known the Hofmann type complexes. The Hofmann-type complexes consist of the
corrugated |M–Ni(CN)4|∞ polymeric layers
which are held in parallel through the Van der Walls interactions of
(-M-Benzoyl chloride...Benzoyl chloride-M-) in our new Hofmann type complexes formed by
bounding electrons of oxygen-donor atoms of the carbonyl group of Benzoyl
chloride ligand to transition metal atoms.
