Carbonyl complexes of platinum(0): synthesis and structure of [(Cy3P)2Pt(CO)] and [(Cy3P)2Pt(CO)2

The platinum(0) monocarbonyl complex, (Cy(3)P)(2)Pt(CO)], was synthesized by reaction of (Cy(3)P)(2)Pt] with (η(5)-C(5)Me(5))Ir(CO)(2)] and subsequent irradiation. X-ray structure analysis was performed and represents the first structural evidence of a platinum(0) monocarbonyl complex bearing two free phosphine ligands. Its corresponding dicarbonyl complex (Cy(3)P)(2)Pt(CO)(2)] was synthesized by treatment of (Cy(3)P)(2)Pt] with CO at -40 °C and confirmed by X-ray structure analysis.
