摘要：
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. © 1978.
