Résumé

The title compound, [FePt(C12H12O)(C18H15P)(C25H22P2)(CO)(2)]center dot 2C(7)H(8)-CH2 Cl-2 or [(OC)(2)Fe(mu-dppm)(mu-C(=O)C(2,4,5-C6H2Me3)=CH)Pt(PPh3)], 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 mu(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 dimetallacyclopentenone ring, in which the C=C bond is pi-coordinated to the Fe centre. The latter is connected to the Pt centre through a short metal-metal bond of 2.5770 (5) angstrom. In the crystal, the complex is solvated by one dichloromethane and two toluene molecules.
