摘要: Abstract By slowly decomposing zirconium fluoro-complexes in the presence of hydroxymethane phosphonic acid, benzene acid or triethylphosphate, micro-crystalline compounds with formulae Zr(HOCH 2 PO 3 ) ·H O, Zr(C 6 H 5 and OPO respectively are formed. Crystals suitable size for X-ray crystal structure determination were not obtained but several experimental observations such as shape crystals, linear relation between first d -value patterns formula-weight/density ratio, discontinous change during dehydration O well intercalation organic molecules provides strong evidence that these materials possess a layered phosphate type. The possibility to obtain other Zr(R-PO Zr(R-OPO inorganic-organic ion-exchangers their possible applications finally discussed.
