Vibrational spectroscopic investigation of some Hofmann type clathrates: M(4-phenylpyridine)2Ni(CN)4.2G (M = Ni, Co and Cd, G = 1,4-dioxane)

Abstract

New Hofmann type clathrates in the form of M(4-Phpy)₂Ni(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.

KEY WORDS: Hofmann type clathrates, Vibrational spectra, 4-Phenylpyridine, 1,4-Dioxane
