The preparation of multicomponent metal oxides from molecular precursors has several advantages including better control over stoichiometry and homogeneity. Another advantage is the ability to modify the structure of the final solid state material by coordination of an appropriate structure-modifying agent to the precursor. Our effort in this area has included the preparation of zinc cluster containing the O{sub 2}P(O{sup t}Bu){sub 2} ligand as a precursor to Zn{sub x}P{sub y}O{sub z} materials. This precursor can be transformed under mild conditions to a polymer or a layered material without loss of the organic groups. At low temperatures (134{degrees}C) the organic groups thermally eliminate isobutylene and water to form Zn{sub x}P{sub y}O{sub z} materials. The structure of the resulting inorganic material can be modified by the use of templating agents. Attempts to prepare ordered phosphate materials containing Al, Zr, and Ti will also be described.
