DOIAbstract
Reaction between CdCl2·H2O and NaH2PO4·H2O under hydrothermal conditions gives rise to a new cadmium chlorophosphate of the formula Na3[Cd4Cl3(HPO4)2(H2PO4)4], I. This material crystallizes in the orthorhombic system with space group Fmm2 (no. 42). I has macroanionic layers of [Cd4Cl3(HPO4)2(H2PO4)4]3− with Na+ ions in the interlamellar space. The discovery of such compounds suggests that metathetic reactions carried out under hydrothermal conditions may provide a novel route for the synthesis of new open-framework structures
