摘要: 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 bimetallic activation metal-coordinated carbonyl ligand with an internal alkyne, namely 1,4-bis(p-tolylthio)but-2-yne. bridging μ2-C(=O)C(CH2SC6H4Me-4)=CCH2SC6H4Me-4 unit (stemming carbon–carbon coupling reaction between CO and triple bond alkyne dithioether) forms five-membered ring, in which C=C is π-coordinated to Fe center. latter connected Pt center through short metal–metal 2.5697 (6) A.
