Abstract
An aqueous ammonium acetate buffer solution (pH 4) containing vanadate, tungstate and dithionite ions, on heating at 100 °C for 1 h yields one-dimensional polyoxometalate chain compound (NH4)4.68[(VVO4) W8VIM4O36(VIV O)2] · 12H2O (M = 0.71VIV + 0.29WVI) 1, which is characterized by single-crystal x-ray structure determination, redox titration, and IR spectroscopic studies. Crystallographic data for 1, H42.72N4.68O54V5.84 W9.16, tetragonal, space group I4̄, a = 15.8132(5), c = 11.1114(5) Å, Z = 2, V = 2778.5(2) Å3. © 2002 Elsevier Science B.V. All rights reserved.
