摘要：
(Figure Presented) Layer apparent: Crystalline cerium(IV) phosphates have been studied for a long time as ion exchangers, but their structures have remained unknown. The structure of a cerium(IV) phosphate has been determined (see picture: tetrahedra PO4, yellow Ce, blue O (water)) and clearly explains a notable feature of this compound, its inability to intercalate amines. The X-ray study is supported by solid-state NMR spectroscopy investigations. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
