The 58-electron cationic cluster complex [Pt4(µ-H)(µ-CO)2(µ-dppm)3(dppm-P)]+, dppm = Ph2PCH2PPh2, has been characterized in solution by n.m.r. spectroscopy and in the solid by X-ray analysis of the PF6– salt; the cation displays novel fluxionality with rapid rotation of a µ-H below and a µ-Pt(CO)2(dppm-P) unit above a Pt3(µ-dppm)3+ triangle.
