Abstract
The complex anions [Pt2X4(CO)2]2–(X = Cl or Br) are formed in solution by the reaction of CO with [PtX4]2– ions in concentrated aqueous HX. Their tetra-n-propylammonium salts have been isolated. Vibrational spectra indicate that the structure of the anions consists of two planar [PtX2CO]– units linked by a platinum–platinum bond. Two forms of the salt (Prn 4N)2[Pt2Cl4(CO)2] have been crystallised, both apparently containing anions with the same symmetry but having different vibrational frequencies, suggesting that the two PtX2CO planes are rotated 45° with respect to each other. The Pt–Pt bond is cleaved by Cl2, HCl, H2, and MeHgCl.Keywords
