Polyoxoalkoxy molybdenum and vanadium clusters

While the chemistry of polyoxoanions has been extensively studied, the related polyoxoalkoxide clusters remain relatively unexplored. Recent investigations into the coordination chemistry of polyoxoanions with alkoxide ligands demonstrate the existence of a rich structural chemistry which is now emerging. The introduction of alkoxide ligands into polyoxoanion cores significantly expands the structural diversity of the cluster types and allows the isolation not only of fully-oxidized cores with all metal centers possessing d⁰ electronic configurations but of fully-reduced and mixed valence systems.
