Organoarsonate Functionalization of Heteropolyoxotungstates.

ABSTRACT: Functionalization of the {P₈W₄₈} polyoxotungstate (POT) archetype with aromatic organoarsonates results in the first homometallic {P₈W₄₈} derivatives, with the general formula [(RAs^VO)₄P^V₈W^VI₄₈O₁₈₄]^32- [R = C₆H₅ (1) or p-(H₂N)C₆H₄ (2)]. Short As-O bonds here induce unusual bending of the otherwise rigid {P₈W₄₈} macrocycle, breaking its D_4h symmetry. The obtained species also represent the first lacunary POTs functionalized with organoarsonates and can potentially act as polyoxometalate precursors themselves. We elaborate solution stability in different aqueous media using <
