Dithiolene transfer to the molybdenum nitrosyl complex [CpMo(CO)2(NO)]: Formation of bimetallic complexes

The nitrosyl complex [CpMo(CO)2(NO)] (Cp = η-C5H5) reacts with the nickel dithiolene complex [Ni(S2C2Ph2)2] to give the expected dimolybdenum complex [Mo2(NO)2(μ-S2C2Ph2)2Cp2], but the major product consists of two separable isomers of the tetranuclear complex [Mo2Ni2(NO)2(μ-S2C2Ph2)4Cp2], which comprises two CpMo(NO)Ni(S2C2Ph2)2 units joined through bridging sulfur atoms.129
