Summary
The i.r. spectra (4000-90 cm−1) of the [Pt(Him)4]X2 complexes (Him = imidazole, X = Cl, Br or I) andcis- andtrans-[Pt(Him)2X2] (X = Cl, Br, I or NO2) and their D3-labelled analogues have been determined. The distinction between the ring and C-H (or N-H) modes of imidazole is based on the relative shifts which these bands undergo on D3-labelling. Assignments, based on the effects of imidazole deuteriation and halide substitution, are provided for the v(Pt-Him) and v(Pt-X) modes.
