A transition metal substituted into the heteropoly tungstate addendum provides a direct covalent coordination site where weak ligands such as carbon dioxide bind in the absence of stronger Lewis bases. This occurs in nonpolar solvents, where the polytungstate anions are soluble with tetraheptylammonium counterions. These species can be reduced in water, then transferred to the nonpolar solvent, or photoreduced in situ. The reduced polyanion apparently reduces carbon dioxide. The activities of several catalytsts are discussed.
