Treatment of [Cp*Ir(µ-SH)3IrCp*]Cl (Cp* = η5-C5Me5) with acrylonitrile and NEt3 in MeCN or ClCH2CH2Cl gave [Cp*Ir(µ-SCH2CH2CN)3IrCp*]+, [Cp*Ir(µ-S)(µ-SCH2CH2CN)2IrCp*] (3), or [Cp*Ir(µ-SCH2CH2CN)2(µ-SCH2CH2Cl)IrCp*]+, depending upon the conditions employed. From the reaction of 3 with [(Cp*Ru)4(µ-Cl)4], a sulfido-thiolato cluster [Cp*3RuIr2(µ3-S)(µ-SCH2CH2CN)2Cl] was obtained.Key words: diiridium complex, thiolate, sulfide, ruthenium, cluster.
