Reactions of the terminal molybdenum phosphido compounds [CpMo(CO)(2)P(Cl)TMP}] (1, TMP = 2,2,6,6-tetramethyl-1-piperidyl) and [Cp*Mo(CO)(3)P(Cl)(NPr2)-Pr-i}] (3) with Co-2(CO)(8) lead to the heterobimetallic phosphinidene bridged compounds [CpMoCo(CO)(5)mu-P(TMP)}] (4a) and [Cp*MoCo(CO)(5)mu-P((NPr2)-Pr-i)}] (4b). Under photolysis, 1 and [CpMo(CO)(3)P(Cl)(NPr2)-Pr-i}] (2) react with Mn-2(CO)(10) and [CpMo(CO)(3)](2) to form the hetero- and homo-bimetallic phosphinidene bridged complexes [CpMoMn(CO)(6)(mu-PNR2)] (5a, NR2 = TMP; b, NR2 = (NPr2)-Pr-i) and [CpMo(CO)(2)}(2)mu-PNR2}] (6a, b). Thermolysis of 1 with Ru-3(CO)(12) leads to the heterotrimetallic cluster [CpMoRu2(CO)(8)(mu-H)mu(3)-P(TMP)}] (7a), while thermolysis of 2 with Ru-3(CO)(12) leads to [CpMoRu2(CO)(8)(mu-H)(mu(3)-(PNPr2)-Pr-i)] (7b) and the ruthenium clusters [Ru-5(CO)(15)mu(4)-(PNPr2)-Pr-i}] (8), [Ru-3(CO)(9)(mu-H)(2)(mu(3)-(PNPr2)-Pr-i)] (9), and [Ru-3(CO)(9)(mu(3)-(PNPr2)-Pr-i)(2)] (10) (C) 2003 Elsevier Science B.V.
