Today, the bimetallic palladium-based carboxylic complexes shown high reactivity in homogeneous catalytic hydrogenation processes of unsaturated hydrocarbons, and their effectiveness as precursors of supported heterogeneous bimetallic catalysts with improved activity and selectivity.
Until recently, convenient single-molecular precursors of the supported catalysts, platinum-based carboxylates were not available because of inaccessibility and low reactivity of the starting material platinum acetate [Pt4(OOCMe)8].
In this work, we synthesized more than 20 novel homo- and heterometallic acetate complexes of platinum and some their derivatives with N-donor ligands. Two synthetic approaches were developed based on the platinum acetate blue (PAB, Pt(OOCMe)2.25-2.75)  and potassium hexahydroxyplatinate K2[Pt(OH)6] [2,3] as starting materials. The structures of the complexes were esrablished by conventional single-crystal X-ray diffraction technique and with using synchrotron radiation single crystal XRD methods.
