Abstract: The title compound, [PtRe(C₅H₅)(C₈H₆)(C₁₈H₁₅P)₂(CO)₂]·0.5C₄H₁₀O, represents the first example of a structurally characterized -vinylidene Re-Pt complex, and was obtained as a product of the addition of [Pt(PPh₃)]₂ to (⁵-C₅H₅)(CO)₂Re=C=CHPh. The two metal atoms are bridged by the -phenylvinylidene ligand. The central fragment of the molecule is an almost planar methylenedimetallacyclopropane RePt(-C=CHPh) system. The Re atom is bonded to the ⁵-C₅H₅ ring and two CO groups, one of which has a tendency to a weak semi-bridging interaction with the Pt atom. The distorted square-planar coordination of the Pt atom is formed by the two P atoms of the PPh₃ ligands, and by two C atoms of the C=CHPh ligand and one of the CO ligands. The solvent molecule is disordered equally over two positions.
