Preparation and Structure of Oxo-bridged Dinuclear Vanadium(III) Complex [VIII2(<scp>l</scp>-his)4(μ-O)]·2H2O

Abstract

Abstract 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.
