PasynskyAbstractBy the reaction of tetramer [Me3Pt(μ3-Cl)]4 with RhCl3 and [PPN]Cl (PPN = Ph3P = N=PPh3+) in a acetone-DCM mixture under the influence of ultrasound a heterometallic ionic complex [PPN][Me3Pt(μ-Cl)3Rh(μ-Cl)3PtMe3] (I) have been prepared. Tetranuclear complex [PPN]2 [(Me3Pt)2Ru2(μ-O)(μ-Cl)6Cl4]2- (II) have been obtained in a small yield starting from RuCl3 in similar conditions. Complex II has also been prepared purposefully in higher yield by the action of Me3Pt(Me2CO)3][PF6] on [PPN]4[Ru2OCl10]. Both complexes were characterized by elemental analysis, 1H, 13C, and 195Pt NMR spectroscopy, and their structures were determined by single crystal X-ray diffraction.Graphical abstract
