The wheel-shaped Cu20 tungstophosphate [Cu20Cl(OH) 24(H2O)12(P8W48O 184)]25- ion

Abstract

(Chemical Equation Presented) Anions get wheely big: A Cu 20-containing polyoxotungstate of large size and high symmetry was synthesized by making use of the template effect. The wheel-shaped [Cu 20CI(OH)24(H2O)12(P 8W48O184)]25- ion (see picture; black W, turquoise Cu, yellow P, violet Cl, red O) is the first transition-metal-substituted derivative of [H7P8W 48O184]33- and incorporates more paramagnetic 3d metal ions than any other polyoxotungstate to date. © 2005 Wiley-VCH Verlag GmbH & Co.
