This study presents a methodology for the synthesis of the ionic cyclopropenium-derived triplatinum cluster complex [(Ph3C3)2Pt3(MeCN)4]2+(BF4–)2 and its analogue with the replacement of one of the BF4– anions with a Cl– anion, which represents a chain coordination polymer in crystalline form. The structures of the complexes were studied by several physicochemical methods, primarily X-ray diffraction using synchrotron radiation and 195Pt NMR spectroscopy in solution with measurement and analysis of the 195Pt–195Pt and 13C–195Pt spin–spin coupling constants. In addition, a high catalytic activity of the synthesized Pt3 complex was observed in hydrosilylation reactions. The catalytic efficiency of the complex was found to be comparable to that of Karstedt’s catalyst and in some cases even higher.
