<b>Vibrational spectroscopic investigation of some Hofmann type clathrates: M(4-phenylpyridine)<sub>2</sub>Ni(CN)<sub>4</sub>.2G (M = Ni, Co and Cd, G = 1,4-dioxane) </b>

Abstract

New Hofmann type clathrates in the form of M(4-Phpy) 2 Ni(CN) 4 .2G (where 4-Phpy = 4-phenylpyridine, G = 1,4-dioxane and M = Ni, Co and Cd) have been prepared in powder form and their FT-IR and Raman spectra have been reported. The results suggest that these compounds are similar in structure to the Hofmann type clathrates and their structures consist of polymeric layers of |M-Ni(CN) 4 | ∞ with the 4-Phpy bound to the metal (M) atom.
