摘要
The title compound, [PtRe(C5H5)(C8H6)(C18H15P)(2)(CO)(2)].-0.5C(4)H(10)O, represents the first example of a structurally characterized mu-vinylidene Re-Pt complex, and was obtained as a product of the addition of [Pt(PPh3)](2) to (eta(5)-C5H5)(CO)(2)-Re =C=CHPh. The two metal atoms are bridged by the mu-phenylvinylidene ligand. The central fragment of the molecule is an almost planar methylenedimetallacyclopropane RePt(mu-C=CHPh) system. The Re atom is bonded to the eta(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.
