摘要

Heteropoly molybdate(VI) and tungstate(VI) anions are typically ionic oxometallate clusters of high symmetry, large size, and high ionic weight. They are usually the anions of strong acids, they form salts that are soluble in a variety of aqueous and nonaqueous solvents, and they may also undergo a series of reversible electron transfer reactions to yield mixed valence (V, VI) heteropoly blues. It has been customary to represent the structures of heteropoly anions as assemblages of metal-oxygen polyhedra which share corners, edges and occasionally faces, and to invoke electrostatic arguments (Pauling's Rules) to rationalize bond-lengths and angles.
