摘要：

The trivanadium-substituted heteropolytungstates M(5)H(3)GaW(9)V(3)O(40).xH(2)O (M = Me(4)N, Et(4)N or K) have been prepared from their lacunary precursor, alpha-Na9GaW9O34H2, and characterized by elemental analysis, V-51- and W-183-n.m.r, spectroscopy, and electrochemistry. The W-183-n.m.r. spectrum of the title anion consists of two lines as expected for the C-3 upsilon structure of the trisubstituted A-alpha-Keggin anion.
