350002) A novel polyoxovanadium borate H3{[Cu(en)2]5[(VO)12O6B18O42]}[B(OH)3]2 has been synthesized from a mixture of H3BO3, NH4VO3, Cu(CH3COO)2·H2O and ethylenediamine under hydrothermal condition and characterized by crystal X-ray structure analysis, IR spectrum, Raman spectrum, UV-Vis DRIS spectrum, fluorescence spectrum,ESR and TGA. In the structure of the compound, there is a ring of B18O42 sandwiched between two vanadium oxygen clusters V6O18 by eighteen B—(μ3O)—V bonds, and the anion clusters [(VO)12O6B18O42]13- are connected through four [Cu(en)2]2+ by the static electronic interaction. Thus, the complex was extended to an infinite two dimensional network structure, with size of the hole amounting to 0.619～1 817 nm.

Key words: hydrothermal synthesis, polyoxovanadium borate, crystal structure, cluster compound
