Abstract
The title compound, [PtRe(C5H5)(C8H6)(C18H15P)2(CO)2]·0.5C4H10O, represents the first example of a structurally characterized μ-vinylidene Re–Pt complex, and was obtained as a product of the addition of [Pt(PPh3)]2 to (η5-C5H5)(CO)2Re=C=CHPh. The two metal atoms are bridged by the μ-phenylvinylidene ligand. The central fragment of the molecule is an almost planar methylenedimetallacyclopropane RePt(μ-C=CHPh) system. The Re atom is bonded to the η5-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.
