Five new types of microporous beryllophosphates were hydrothermally synthesized using BeO-P2O5-R-MCl (or MCl2)-H2O, R being cyclohexylamine (CHA), pyrrolidine, 1-butylamine or triethylamine, M alkali or alkali earth cation. X-Ray diffraction patterns (XRD), infrared (IR), TG-DT and elemental analysis show that the crystalline beryllophosphates have novel, unique framework structures, composed from basic units of tetrahedral PO4 and BeO4. These materials exhibit zeolite-like adsorption and ion-exchange properties. Factors affecting the product crystallization (as e.g. pH), type of cation and composition of reaction mixture are discussed.
