摘要：
The compound [Zn(H2O)(4)](2)[H2As6V15O42(H2O)].2H(2)O (1) has been synthesized and characterized by elemental analysis, IR, ESR, magnetic measurement, third-order nonlinear property study and single crystal X-ray diffraction analysis. The compound 1 crystallizes in trigonal space group R3, a = b = 12.0601(17) Angstrom, c = 33.970(7) Angstrom, gamma = 120degrees, V = 4278.8(12) Angstrom(3), Z = 3 and R1(wR2) = 0.0512 (0.1171). The crystal structure is constructed from [H2As6V15O42(H2O](4-) anions and [Zn(H2O)(4)](2+) cations linked through hydrogen bonds into a network. The [H2As6V15O42(H2O)](6-) cluster consists of 15 VO5 square pyramids linked by three As2O5 handle-like units. (C) 2003 Elsevier B.V. All rights reserved.
