The Infrared spectra of M(4phenylpyridine)2 Ni(CN)4, (M=Fe, Co, Zn or Cu) complexes and the new

HofmannTdtypehost complex, Cd (dioxan) Cd(CN)4 are reported. The structure of 4phenylpyridine

complexes consists of corrugated polymeric layers of [M Ni(CN)4]∞ with 4phenylpyridine

molecules bound directly to the metal (M). The metal sensitivity sequence of the 4phenylpyridine

frequencies is found to be Fe < Co < Zn < Cu. Spectral data of Cd(dioxan)Cd(CN)4 complex indicate that the dioxane

molecules bound to two identical metal(Cd) atoms through both oxygen atoms and it is present in the

chair conformation. The framework of the complex is similar to those found in HofmannTd

type clathratrate compounds.
