Unprecedented Formation of Dinuclear Platinum(II) Complexes with μ-Alkenylidene Bridging Ligands from Reactions of Pt(dppm)2Cl2 with Alkyl Acetylenes

A new series of dinuclear platinum(II) complexes, [Pt2(μ-dppm)(dppm-P,P‘)(μ-CCRPPh2CH2PPh2-P)(C⋮CR)]2+ (R = alkyl), has been synthesized, and the structure o...
