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.
