Introducing Chirality into Hybrid Clusters from an Achiral Ligand: Synthesis and Characterization of Polyoxomolybdates Containing a Benzylarsonate Group

Benzylarsonic acid as a flotation collector was introduced into polyoxometalate chemistry and two new hybrid clusters, [(C6H5CH2AsO3)2Mo5O15]4– (1a) and [(C6H5CH2AsO3)4Mo12O34]4– (2a), were synthesized and characterized by chemical and spectral analysis. Self‐assembly of 1a led to chiral crystals of...

Description
Summary:Benzylarsonic acid as a flotation collector was introduced into polyoxometalate chemistry and two new hybrid clusters, [(C6H5CH2AsO3)2Mo5O15]4– (1a) and [(C6H5CH2AsO3)4Mo12O34]4– (2a), were synthesized and characterized by chemical and spectral analysis. Self‐assembly of 1a led to chiral crystals of compound 1, whereas compound 2 was found to be a racemic mixture of the “inverted‐Keggin” hybrid cluster of 2a. Both compounds were characterized in the solid state, and their redox properties were examined. Benzylarsonic acid is introduced into polyoxometalate chemistry, and two new chiral hybrid clusters are synthesized and characterized.
