Isolable mono(metallo)stibanes of the type [M]Sb(CF3)2 ([M] = (CO)5Mn (3a), (CO)5Re (3b), Cp(CO)3Cr (3c), Cp(CO)3Mo (3d), C5Me5(CO)3W (3e)) are formed quantitatively by reactions of Sb(CF3)3 (1) with the corresponding hydride complexes [M]H (2) with elimination of trifluoromethane. Structural analyses of the derivatives 3a and 3e by X-ray diffraction show a considerable shortening of the M−Sb bonds in comparison with the sum of the single bond radii. In the crystal lattice of 3a a significant intermolecular Sb···Sb interaction of pairs of molecules is observed.
