Crystal structure of {?2-1,2-bis-[(4-methyl-phenyl-sulfan-yl]-3-oxoprop-1-ene-1,3-di-yl-1:2?2 C 3:C 1}dicarbon-yl-1?2 C-[?2-methyl-enebis(di-phenyl-phos-phane)-1:2?2 P:P'](tri-phenyl-phosphane-2?P)iron-platinum(Fe-Pt), [(OC)2Fe(?-dppm){?-C(=O)C(4-MeC6H4SCH2)=CCH2SC6H4Me-4}Pt(PPh3)].


ABSTRACT: The title compound, [FePt(C19H18OS2)(C18H15P)(C25H22P2)(CO)2], 1, [(OC)2Fe(?-dppm)(?-C(=O)C(CH2SC6H4Me-4)=CCH2SC6H4Me-4)Pt(PPh3)], represents the first example of a diphosphane-bridged heterobimetallic Fe-Pt dimetalla-cyclo-pentenone complex resulting from a bimetallic activation of metal-coordinated carbonyl ligand with an inter-nal alkyne, namely 1,4-bis-(p-tolyl-thio)-but-2-yne. The bridging ?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 di-thio-ether) forms a five-membered dimetalla-cyclo-pentenone ring, in which the C=C bond is ?-coordinated to the Fe center. The latter is connected to the Pt center through a short metal-metal bond of 2.5697?(6)?Å.
