Crystallization Pathways of Cerium(IV) Phosphates Under Hydrothermal Conditions: A Search for New Phases with a Tunnel Structure , (2019)
аннотация
Hydrothermal crystallization pathways of amorphousceric phosphate gels were found to be determined by ammonia concentration in a reaction medium. This allows forhighlyselective hydrothermal synthesis of various finely crystalline ceric phosphates,including Ce(PO4)(HPO4)0.5(H2O)0.5, (NH4)2Ce(PO4)2(H2O) andpreviously unknown NH4Ce2(PO4)3. The structure of the latter compound was solvedfrom powder X-ray diffraction data. It appeared to be isostructural to ammonium thorium phosphate, NH4Th2(PO4)3; in this crystal structure, large channels (5.07 -3.79 Å) located along the c-axis are occupied by NH4+ions
