Abstract The infrared spectra of M(4,4′-bipyridyl)Ni(CN)4 complexes (M=Ni or Cd) and their dioxane, benzene, toluene, aniline andN,N-dimethylaniline clathrates are reported. Additional information regarding the structure of the host lattice is obtained from the Raman spectra of the M=Cd complex. It is shown that the structure of the host lattice consists of infinite polymeric layers of {M-Ni(CN)4}∞ analogous to those of Hofmann type clathrates that have tetragonal symmetry. Bidentate 4,4′-bipyridyl molecules form bridges between the metal atoms {M} in the adjacent {M-Ni(CN)4}∞ layers. It is found that the 4,4′-bipyridyl molecules are centrosymmetric in this structure.
