Abstract

The [VOCl₄]^2–/AgOAc reaction system in MeCN gives [V₅O₉Cl(OAc)₄]^2–, [V₉O₁₉(OAc)₅]^3– and [V₁₅O₃₆]^5– for reagent ratios of 1∶2, 1∶3 and 1∶4, respectively: the V₅ and V₉ cores are fragments of the V₁₅ core, suggesting the V₅ and V₉ units are carboxylate-stabilised intermediates in the assembly of the V₁₅ polyoxovanadate.
