Crystal structure of dicarbon­yl[μ(2)-methyl­enebis(di­phenyl­phosphane)-κ(2) P:P′][μ(2)-2-(2,4,5-tri­methyl­phen­yl)-3-oxoprop-1-ene-1,3-di­yl](tri­phenyl­phosphane-κP)ironplatinum(Fe—Pt)–di­chloro­methane–toluene (1/1/2), [(OC)(2)Fe(μ-dppm)(μ-C(=O)C(2,4,5-C(6)H(2)Me(3))=CH)Pt(PPh(3))]

The title compound, [FePt(C(12)H(12)O)(C(18)H(15)P)(C(25)H(22)P(2))(CO)(2)]·2C(7)H(8)·CH(2)Cl(2) or [(OC)(2)Fe(μ-dppm)(μ-C(=O)C(2,4,5-C(6)H(2)Me(3))=CH)Pt(PPh(3))], represents an example of a diphosphane-bridged heterobimetallic dimetalla­cyclo­pentenone complex resulting from a bimetallic activation of 1-ethynyl-2,4,5-tri­methyl­benzene and a metal-coordinated carbonyl ligand. The bridging μ(2)-C(=O)C(2,4,5-C(6)H(2)Me(3))=CH unit (stemming from a carbon–carbon coupling reaction between CO and the terminal alkyne) forms a five-membered dimetalla­cyclo­pentenone ring, in which the C=C bond is π-coordinated to the Fe centre. The latter is connected to the Pt centre through a short metal–metal bond of 2.5770 (5) Å. In the crystal, the complex is solvated by one di­chloro­methane and two toluene mol­ecules.
