The reactions of some phosphine selenides with mononuclear and dinuclear manganese complexes have been investigated. The reactions of Cp′Mn(CO)2(THF) (1) with bis(diphenylphosphino)ethane diselenide (dppeSe2) affords [(Cp′Mn)2(μ-Se) 2(CO)2(dppe)] (4), identified by spectroscopic techniques. Complex CpMn(CO)2(THF) (2), by reacting with bis(diphenylphsphino) methane monoselenide (dppmSe) gives a variety of products, [(CpMn) 2(μ-Se)2(CO)3(dppm)] (5), [CpMn(CO) 2(dppm)] (6), [(CpMn)2(CO)4(μ-dppm)] (7), [CpMn(CO)2(dppmSe)] (8) have been identified (Cp=η 5-C5H5, Cp′=η5-C 5H4Me, THF=tetrahydrofuran). Finally the reactions of [Mn2(CO)8(MeCN)2] (3) with diphenylmethylphosphine selenide (dpmpSe) and triphenylphosphine selenide (tppSe) afford clusters with molecular formula [Mn4(μ 3-Se)2(μ-CO)(CO)14(dpmp)2] (9) and [Mn4(μ3-Se)2(μ-CO)(CO) 14(tpp)2] (10), respectively. The structure of 9 has been determined by X-ray diffraction methods.
