摘要：

Six of the best! Two Zr6- and Hf6-containing tungstoarsenates(III) [M6O4(OH)4(H 2O)2(CH3COO)5(AsW9O 33)2]11- (M=Zr, Hf) have been synthesized and structurally characterized in solution and in the solid state, and both species are highly active in H2O2-based selective oxidations. © 2010 WILEY-VCH Verlag GmbH & Co.
