Abstract：
Three polyoxovanadium clusters, [{Ni(phen)2}2V4O12] ·H2O I, [N(CH2CH2)3NH] Na(H2O)6 {K4(H2O)4[V10 O28]}(H2O)4 II and [(CH3)4N]6 [V15O36Cl] III, have been synthesized under hydrothermal condition. The relationship between their properties and structures were studied by using FTIR, UV-Vis DRS and flurescence. The FTIR showed that the vibrational frequencies of the group are related to the structure of the materials. In UV-Vis DRS spectra of compound I, there are four characteristic wide peaks at 200, 230, 260 and 350 nm corresponding to Ot-＞V, Oμ-＞Ni, Oμ-＞V charge transfer and phen＇s π-π*, respectively. The fluorescence spectra of clusters have been studies. Finally, the quantum chemistry calculation was performed by Gaussian 98 program to explain the structure characteristic of compound I.
