Crystal structure of dicarbon-yl[?2-methyl-enebis(di-phenyl-phosphane)-?2 P:P'][?2-2-(2,4,5-tri-methyl-phen-yl)-3-oxoprop-1-ene-1,3-di-yl](tri-phenyl-phosphane-?P)ironplatinum(Fe-Pt)-di-chloro-methane-toluene (1/1/2), [(OC)2Fe(?-dppm)(?-C(=O)C(2,4,5-C6H2Me3)=CH)Pt(PPh3)].

ABSTRACT: The title compound, [FePt(C12H12O)(C18H15P)(C25H22P2)(CO)2]·2C7H8·CH2Cl2 or [(OC)2Fe(?-dppm)(?-C(=O)C(2,4,5-C6H2Me3)=CH)Pt(PPh3)], represents an example of a diphosphane-bridged heterobimetallic dimetalla-cyclo-pentenone complex resulting from a bimetallic activation of 1-ethynyl-2,4,5-tri-methyl-benzene and a metal-coordinated carbonyl ligand. The bridging ?2-C(=O)C(2,4,5-C6H2Me3)=CH unit (stemming from a carbon-carbon coupling reaction between CO and the terminal alkyne) forms a five-membered dimetalla-cyclo-pentenone ring, in which the C=C bond is ?-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 di-chloro-methane and two toluene mol-ecules.
