The IR and Raman spectra of [Pt(C2H4)3], [Pt(C2D4)3] and IR spectra of [Ni(C2H4)3] are reported and assignments proposed. Comparisons are made with previously reported IR spectroscopic features of Pd, Co and Cu analogues. The results of a CNDO/2 geometry optimization calculation for [Ni(C2H4)3] are summarized, and reveal closely similar structural parameters for the ethylene ligand to those established for the Pt complex. Some comparisons are made between vibrational frequencies of the complexes and those of ethylene chemisorbed on single crystal metal surfaces.
