The syntheses of [Mn2(CO)10-x(SbPh3)x] (x=1 or 2), [Re2(CO)9(SbPh3)], [Mn(CO)5(SbPh3)][CF3SO3], [M(CO)4Cl(SbPh3)], fac-[M(CO)3Cl(SbPh3)2] (M=Mn or Re) and mer,trans-[Mn(CO)3Cl(SbPh3)2] are reported. The complexes have been characterised by chemical analysis, IR and multinuclear NMR (1H, 13C{1H} and 55Mn) spectroscopies, and FAB mass spectrometry. The crystal structure of [Mn2(CO)9(SbPh3)] established the axial position of the SbPh3 ligand (Mn-Sb 2.525(1), Mn-Mn 2.909(1) A) and that of [Mn(CO)5(SbPh3)][CF3SO3] confirmed the cation structure (Mn-Sb 2.596(3) A). The crystal structure of fac-[Re(CO)3Cl(SbPh3)2] establishes the stereochemistry (Re-Sb 2.726(1), 2.729(2) A). Differences in the products/isomers produced in reactions of [M2(CO)10] and [M(CO)5Cl] with SbPh3 and with the corresponding PR3 and AsR3 ligands are identified and discussed.
