The IR spectra (33-4000 cm-1) and the RAMAN spectra (0-2500 cm-1) of the complexes M(II)[Pt(CN)6] (M = Mg, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd) have been recorded. In the region 33-300 cm-1, the IR spectra of the isotopic compounds with 64Zn and 68Zn68Zn and with 58Ni and 62Ni have been obtained. The observed frequencies are assigned to the normal modes of the lattices. A normal coordinate analysis has been carried out for the above coordination polymers. The force constants of the Pt(CN)6

The valency force constants of the coordinative bonds M(II)-N are in the range 0,1-1 mdyn/Å. This variability is considered to stem primarly from ligand field effects.
