A new bimetallic cluster complex with the formula [{Mn(phen)2}2V4O12]•1/2 H2O has been synthesized through hydrothermal reaction of vanadate staring material with manganese cation in the presence of nitrogen donor chelating ligand and characterized by single-crystal X-ray diffraction, elemental analysis, IR ,UV-vis, ESR spectrum and thermal analysis. The compound crystallize in the monoclinic space group P21/c with a=18.475(4) A˚, b=11.473(2) A˚, c=23.667(5) A˚, β=97.76(3)°, V=4971(2) A˚3 and Z=4. The structure of [{Mn(phen)2}2V4O12]•1/2 H2O is composed of a discrete V4O4−12 cluster covalently attached to two [Mn(phen)2]2+ fragments. [ABSTRACT FROM AUTHOR]
