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