Abstract

Abstract Mo2O4Cl2(bipy)2 has been obtained by oxidation of MoCl4(bipy) with O2 in ethanol/H2O . The complex crystallizes from CH3NO2 with one solvent molecule per formula unit in the monoclinic space group P 21/n: a = 954.1(2), b = 1925.3(2), c = 1423.2(2) pm, β = 102.48(2)°, Z = 4. The characteristic unit Mo2O4 2+ of the dinuclear complex consists of two terminal oxo ligands in a cisarrangem ent and two bridging oxygen atoms forming a non-planar Mo2O2 ring. A strong Mo -Mo single bond is indicated by a short distance of 256.5 pm. The coordination of both Mo atoms is completed by a Cl atom and a chelating bipyridyl ligand.
