 Title    Darstellung, Charakterisierung und Normalkoordinatenanalyse von gemischtvalentem Dodekabromotriplatinat(IV,II,IV) [Pt3Br12]2~ und Kristallstruktur von (Ph3P =N =P P h3)2[Pt3Br12] * 2 CH2C12 Preparation, Characterization and Norm al Coordinate Analysis o f the Mixed Valence Dodecabrom otriplatinat(IV ,II,IV ) [Pt3Br12]2~ and Crystal Structure of (Ph3P = N = PPh3)2[Pt3Br 12] * 2 C H 2C12  
 Abstract    Heating a mixture (2:1) o f the tetrabutylammonium salts (TBA^JPtBrJ and (T B A)2[PtBr4] with trifluoroacetic acid leads to the mixed valence dodecabromotriplatinate(IV,II,IV) (T B A)2[Pt3Br12], The X-ray structure determination o f (Ph3P = N = PPh3)2[Pt3Br12] • 2C H 2C12 (triclinic, P 1, Z = 1) shows trinuclear groups with nearly D 2h symmetry for the anions, formed o f two PtBr6 octahedra and one planar PtBr4 group sharing edges. U sing the structural data a normal coordinate analysis based on a general valence force field for [Pt3Br12]2-has been per­ formed, which gives good agreement o f the calculated frequencies with the bands observed in the IR and Raman spectra.
