Preparation and Structure of Oxo-bridged Dinuclear Vanadium(III) Complex [VIII2(L-his)4(μ-O)]·2H2O

The synthesis, structure, and properties of a L-histidinato vanadium(III) complex, [VIII2(L-his)4O)]·2H2O, are reported. Crystal structure analysis has revealed that the complex is an oxo-bridged dimer with the V-O-V angle of 153.9(2)° and at each vanadium(III) center one L-his ligand coordinated tridentately and the other didentately. The visible absorption and resonance Raman spectra show the characteristic feature of the oxo-bridged vanadium(III) complexes.
