The reactions of cationic alkyne complexes 1)(L2)M(RCCR)>(+) (L1 = CO, PR3, P(OMe)3; L2 = C2Me2, CO, P(OMe)3; M = Mo, W) with (-) or (-) give heterobimetallic tetrahedranes Cp(OC)2M(μ2-η2:η2-RCCR)M'(CO)3L1 (M = Mo, W; M' = Re, Mn) and Cp(OC)2Mo(μ2-η2:η2-MeCCMe)Re(CO)22.Similarly, the reaction of (+) or (+) with(-) provides a rational synthesis of Cp(OC)2Mo(μ2-η2:η2-RCCR)W(CO)2Cp.The dimetallatetrahedranes contain a semibridging CO group.The structures of Cp(OC)2Mo(μ2-η2:η2-H3CCCCH3)Re(CO)4 and Cp(OC)2Mo(μ2-η2:η2-H3CCCCH3)Re(CO)22 have been determined by X-ray crystallography. - Key Words: Heterobimetallic complexes, alkyne-bridged / Carbonyl complexes / Molybdenum / Tungsten / Rhenium
