Self-Assembly and Ionic-Lattice-like Secondary Structure of a Flexible Linear Polymer of Highly Charged Inorganic Building Blocks.

ABSTRACT: Among molecular building blocks, metal oxide cluster anions and their countercations provide multiple options for the self-assembly of functional materials. Currently, however, rational design concepts are limited to electrostatic interactions with metal or organic countercations or to the attachment and subsequent reactions of functionalized organic ligands. We now demonstrate that bridging μ-oxo linkages can be used to string together a bifunctional Keggin anion building block, [PNb₂Mo₁₀O₄₀]^5- (1), the diniobium(V) analogue of [PV₂Mo₁₀O₄₀]^5- (2). Induction of μ-oxo ligation between the Nb^V═O moieties of 1 in acetonitrile via step-growth polymerization gives linear polym
