The title compound, [FePt(CHOS)(CHP)(CHP)(CO)], , [(OC)Fe(μ-dppm)(μ-C(=O)C(CHSCHMe-4)=CCHSCHMe-4)Pt(PPh)], 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-(-tolyl-thio)-but-2-yne. The bridging μ-C(=O)C(CHSCHMe-4)=CCHSCHMe-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 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.
标题化合物[FePt(CHOS)(CHP)(CHP)(CO)]，[(OC)Fe(μ - dppm)(μ - C(=O)C(CHSCHMe - 4)=CCHSCHMe - 4)Pt(PPh)]，是双膦桥联异金属Fe - Pt二金属环戊烯酮配合物的首个实例，它由金属配位的羰基配体与内炔（即1,4 - 双（对甲苯硫基）- 丁 - 2 - 炔）的双金属活化反应生成。桥联的μ - C(=O)C(CHSCHMe - 4)=CCHSCHMe - 4单元（源自CO与炔二硫醚三键之间的碳 - 碳偶联反应）形成一个五元二金属环戊烯酮环，其中C = C键与Fe中心呈π配位。后者通过2.5697(6) Å的短金属 - 金属键与Pt中心相连。
