The nature of the bond between a metal and an unsaturated hydrocarbon is one of the most fundamental and significant problems in coordination chemistry. In spite of wide structural and spectroscopic studies of olephinic π-complexes a number of fundamental spectroscopic properties have not been clearified yet. Reinvestigation of FT-IR and Raman spectra of K[Pt(C2H4)Cl3] and K[Pt(C2H4)Cl3].H20 in both the solid phase and water/HCl solution suggests some modification of widely accepted assignments. Skeletal modes of [NBu4][Pt(C2H4)Br3], [NBu4][Pd(C2H4)Cl3] and their C2D4derivatives have been measured and assigned. A new model for the normal coordinate treatment of π-complexes has been adopted to calculate metal-ligand force constants.
