Abstract

During hydrothermal syntheses of metal phosphates, sulfates or metal carboxylates, intermediate species such as amine phosphates, amine sulfates or amine carboxylates are often formed respectively as additional products. The isolation of the intermediate phase and its reaction with metal ions to form open framework solids has been explored and it has proven a facile route of synthesizing inorganic-organic hybrid materials with open pores. Here the amine phosphate route of templating inorganic open-framework materials has been reviewed. Metal carboxylates with open architectures synthesized via amine oxalate route as well as metal sulfate by amine sulfate route are also discussed.
