K. Jayaraman et al., A layered chlorophosphate, Na-3[Cd4Cl3(HPO4)(2)(H2PO4)(4)], containing Na+ions in the interlamellar space, NEW J CHEM, 25(9), 2001, pp. 1199-1202
Reaction between CdCl2.H2O and NaH2PO4.H2O Under hydrothermal conditions gi
ves rise to a new cadmium chlorophosphate of the formula Na-3[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)(H2
PO4)(4)](3-) with Na+ ions in the interlamellar space. The discovery of suc
h compounds suggests that metathetic reactions carried out under hydrotherm
al conditions may provide a novel route for the synthesis of new open-frame
work structures.
