Reactions of Fe3E2(CO)9 (E = S, Se) with M(PPh3)4 (M = Ni, Pd, Pt), at room temperature, show a marked contrast with the analogous reaction of Fe3Te2(CO)9. Different mechanisms are suggested for the formation of the mixed-metal complexes, Fe2E2(CO)6M(PPh3)2 (E = S, Se, Te; M = Pd, Pt, and E = Te; M = Ni), depending on the chalcogen atom involved. The size of the chalcogen and that of the heterometal
Fe 3 E 2(CO)9(E = S,Se)与M(PPh 3)4(M = Ni,Pd,Pt)在室温下的反应与Fe 3 Te的类似反应形成明显对比2(CO)9。提出了形成混合金属配合物Fe 2 E 2(CO)6 M(PPh 3)2的不同机理(E = S,Se,Te; M = Pd,Pt和E = Te; M = Ni),取决于所涉及的硫属元素原子。硫族元素的大小和杂金属原子的大小在反应结果中起着至关重要的作用。

Room temperature reactions of [Fe3Te2(CO)8(PPh3)] (2) and [(CO)6Fe2PdY2(PPh3)2] (Y = Se (6), Te (7)) with bis-(diphenylphosphino)methane (dppm) in dichloromethane solution led to the formation of a tellurium bridged cluster, [Fe3Te2(CO)8(μ-dppm)] (4) and mixed metal clusters, [(CO)12Fe4Y4Pd2(dppm)2] (Y = Se (8), Te (9)) respectively. In both the reactions, diphosphine incorporation has taken place
[Fe 3 Te 2(CO)8(PPh 3)](2)和[(CO)6 Fe 2 PdY 2(PPh 3)2 ]的室温反应(Y = Se(6),Te(7))与二(二苯基膦基)甲烷(dppm)在二氯甲烷溶液中的溶液形成碲桥接的簇[Fe 3 Te 2(CO)8(μ-dppm)](4)和混合金属簇[ 12 Fe 4 Y 4 Pd 2(dppm)2](Y = Se(8),Te(9))。在两个反应中,通过取代一个或两个三苯基膦配体而发生了二膦的结合。化合物的结构4,6和9进行了结晶学确定。
