The binuclear µ-vinylidene complexes containing an isocyanide ligand (1-(isocyanomethylsulfonyl)-4-methylbenzene) Cp(CO) 2 RePt(μ-C=CHPh)(TosMIC)(L) [L = PPh 3 ( 1 ), P(OPr i ) 3 ( 2)] were synthesized for the frst time. The approach afforded 1 and 2 based on the substitution reactions of a platinum bound carbonyl group in Cp(CO) 2 RePt(μ-C=CHPh)(CO)(L) [L = PPh 3 ( 1a ), P(OPr i ) 3 ( 2a )] upon addition of 1-(isocyanomethylsulfonyl)-4-methylbenzene. The complexes 1 and 2 were characterized by IR and NMR spectroscopy. Their redox properties were studied. Keywords: rhenium, platinum, vinylidene complexes, heterometallic complexes, carbonyl, isocyanide, electrochemistry.
