Abstract:

The dinuclear compound, [Nb(2)Cl(6)(C(2)H(6)S)(1.7)(C(2)H(6)Se)(1.3)], features an Nb(III)=Nb(III) double bond [2.6878 (5) Å]. The mol-ecule lies on a twofold rotation axis that passes through the middle of this bond as well as through the bridging dimethyl sulfide ligand. The Nb(III) ion exists in an octa-hedral coordination environment defined by two terminal and two bridging Cl atoms, and (CH(3))(2)Se/(CH(3))(2)S ligands. The (bridging) ligand lying on the twofold rotation axis is an ordered (CH(3))(2)S ligand, whereas the terminal ones on a general position are a mixture of (CH(3))(2)Se and (CH(3))(2)S ligands in a 0.647 (2):0.353 (2) ratio (the methyl C atoms are also disordered).
