Syntheses and Structures of Organically Templated Iron Phosphates

Iron phosphates are of interest because of rich crystal chemistry and practical applications. New crystalline iron phosphates have been prepared in aqueous or predominantly nonaqueous solvents under mild hydrothermal conditions using organic amines as structure-directing agents. The effects of pH, solvent, and temperature on the reaction products are discussed. FePOs have been prepared with 1-D chain, 2-D layered, and 3-D open framework structures. An FePO containing a chiral amine is also synthesized. This review will summarize some of the results of the work in the area of organically templated iron phosphates.
