Assembly of a family of mixed metal {Mo : V} polyoxometalates templated by TeO32−: {Mo12V12Te3}, {Mo12V12Te2} and {Mo17V8Te}

Abstract

The influence of the pyramidal heteroanion, TeO₃²⁻ in the self-assembly of mixed metal (Mo/V) systems, is demonstrated by the isolation of three novel mixed-metal, mixed-valence architectures, {Mo₁₂V₁₂Te₃} (1), {Mo₁₂V₁₂Te₂} (2) and {Mo₁₇V₈Te} (3) with the tellurium centres exhibiting the novel μ₈-TeO₄ and μ₉-TeO₃ coordination modes while compounds 1 and 2 were discovered utilizing ESI mass spectrometry.
