| Résumé | The title compound, [FePt(C19H18OS2)(C18H15P)(C25H22P2)(CO)(2)], 1, [(OC)(2-)Fe(mu-dppm)(mu-C(=O)C(CH2SC6H4Me-4)=CCH2SC6H4Me-4)Pt(PPh3)], represents the first example of a diphosphane-bridged heterobimetallic Fe-Pt dimetallacyclopentenone complex resulting from a bimetallic activation of metal-coordinated carbonyl ligand with an internal alkyne, namely 1,4-bis(p-tolylthio)but-2-yne. The bridging mu(2)-C(=O)C(CH2SC6H4Me-4)=CCH2SC6H4Me-4 unit (stemming from a carbon-carbon coupling reaction between CO and the triple bond of the alkyne dithioether) forms a five-membered dimetalla-cyclopentenone ring, in which the C=C bond is pi-coordinated to the Fe center. The latter is connected to the Pt center through a short metal-metal bond of 2.5697 (6) angstrom. |
