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)WVI8M4O36(VIVO)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, H42.72N4.68O54V5.84W9.16, tetragonal, space group 1 4, a=15.8132(5), c=11.1114(5) Å, Z=2, V=2778.5(2) Å3.
