Description :
The title compound, [FePt(C19H18OS2)(C18H15P)(C25H22P2)(CO)2], 1, [(OC)2Fe(μ-dppm)(μ-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 μ2-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 dimetallacyclopentenone ring, in which the C=C bond is π-coordinated to the Fe center. The latter is connected to the Pt center through a short metal–metal bond of 2.5697 (6) Å.
