Anisotropic Polyoxometalate Cages Assembled via Layers of Heteroanion Templates.

ABSTRACT: The synthesis of anisotropic redox-active polyoxometalates (POMs) that can switch between multiple states is critical for understanding the mechanism of assembly of structures with a high aspect ratio, as well as for their application in electronic devices. However, a synthetic methodology for the controlled growth of such clusters is lacking. Here we describe a strategy, using the heteroanion-directed assembly, to produce a family of 10 multi-layered, anisotropic POM cages templated by redox-active pyramidal heteroanions with the composition [W₁₆Mo₂O₅₄(XO₃)]^n-, [W₂₁Mo₃O_75/76(XO₃)₂]^m-, and [W₂₆Mo₄O₉₃(XO₃)₃
