Abstract

Detailed i.r. and Raman studies are reported for [AuCl(CO)], [PtX3(CO)]- (X = Cl, Br, or I), [PdX3(CO)]-, cis-[PtX2(CO)2], cis-[RhX2(CO)2]- (X = Cl or Br), and cis-[IrCl2(CO)2]- together with assignments. Skeletal stretching wavenumbers are reported for cis-[PtX2(CO)(PMe3)] (X = Cl, Br, or I), trans-[PtX(CO)(PMe3)2]+, trans-[RhX(CO)(PMe3)2] (X = Cl or Br), and [RhCl3(CO)(PMe3)2]. The results of 13C n.m.r. studies on the carbony complexes are reported together with those from 1H n.m.r. and 1H-{31p} and 1H-{195Pt} INDOR spectroscopy on the phosphine-containing complexes. The 195Pt chemical shifts of [PtX3(CO)]- from direct measurements are reported. The results are discussed with the assistance of stretching force constants for some of the simpler complexes.
