| Abstract: | The IR spectra of cis- and trans-Pt(pyridine)2X2] (X = Cl, Br, I, SCN) are discussed. Distinction between the vPt—N and vPt—X bands is based on their relative sensitivities to 15N-labelling and deuteration of the pyridine ring, to halogen substitution and to 15NCS-labelling. Two vPt—N and two vPt—X bands are observed in the cis-complexes as required for C2v symmetry. The D2h symmetry of the trans-complexes requires one vPt-N and one vPt—X band but additional bands are observed and are ascribed to coupling between vPt—N and vPt—X. |
