摘要：

The compound (enH(2))(3.5)[As8V14O42(PO4)].2H(2)O 1 (en = ethylenediamine) has been synthesized and characterized by means of elemental analysis, IR spectrum, ESR spectrum, XPS spectrum, TG analysis and single crystal X-ray diffraction analysis. The compound 1 crystallizes in monoclinic system, space group C2/c, a= 44.280(9) Angstrom, b = 11.963(2) Angstrom, c = 20.939(4) Angstrom, beta = 105.59(3), V = 10683(4) Angstrom(3), Z = 8 and R-1(wR(2)) = 0.0398(0.0885). The compound 1 is constructed from [As8V14O42(PO4)](7-) anions and H(2)en cations linked through hydrogen bonds into a network. The [As8V14O42(PO4)(7-) cluster consists of 14 VO5 square pyramids linked by 4 As2O5 handle-like units, and includes at its center an ordered PO43- anion. (C) 2003 Elsevier Science B.V.
