| Trivacant lacunary Keggin anions of the form [Xn+W9O34]–(14–n) (X = various main group cations), when reacted with various first row transition metals, form “sandwich”-type polyoxometalates. The α and B-β isomers of these anionic clusters (see figure) have the potential to coordinate to one another through bitopic ligands. This work focused on the preparation of the transition metal-substituted polyoxometalate “sandwiches”, characterized by FTIR and X-ray crystallography. Several organic ligands capable of forming new materials with these inorganic building blocks have also been examined. Characterization of the resulting materials is ongoing.
