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

The influence of the pyramidal heteroanion, TeO(3)(2-) in the self-assembly of mixed metal (Mo/V) systems, is demonstrated by the isolation of three novel mixed-metal, mixed-valence architectures, {Mo(12)V(12)Te(3)} (1), {Mo(12)V(12)Te(2)} (2) and {Mo(17)V(8)Te} (3) with the tellurium centres exhibiting the novel μ(8)-TeO(4) and μ(9)-TeO(3) coordination modes while compounds 1 and 2 were discovered utilizing ESI mass spectrometry.
