Abstract

The compound [Zn(H2O)4]2[H 2As6V15O42(H2O)]· 2H2O (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) Å, c = 33.970(7) Å, γ = 120°, V = 4278.8(12) Å3, Z = 3 and R1(wR2) = 0.0512 (0.1171). The crystal structure is constructed from [H2As 6V15O42(H2O)]4- anions and [Zn(H2O)4]2+ cations linked through hydrogen bonds into a network. The [H2As6V 15O42(H2O)]6- cluster consists of 15 VO5 square pyramids linked by three As2O5 handle-like units.
