Abstract

Four new lead phosphates, A₂PbBi₂(PO₄)₂(P₂O₇) (A = Rb, Cs) and A₂PbP₂O₇ (A = K, Rb), have been synthesized by the high-temperature solution method. A₂PbBi₂(PO₄)₂(P₂O₇) (A = Rb, Cs) compounds are isomorphic and crystallize into the space group of Pnma with different P-O groups, P₂O₇ and PO₄. Rb₂PbBi₂(PO₄)₂(P₂O₇) exhibits an interesting structure that can be regarded as the stacking of Rb₂Pb(P₂O₇) and BiPO₄. A₂PbP₂O₇ (A = K, Rb) compounds crystallize into the same space group of C2/c, but they are not isomorphic and exhibit different Pb-P-O frameworks. The influence of cation on the anion framework of A₂PbP₂O₇ (A = K, Rb) has been discussed. The four compounds all melt congruently. Also, we have studied the cationic influence on the thermal and optical properties of A₂PbBi₂(PO₄)₂(P₂O₇) (A = Rb, Cs) and A₂PbP₂O₇ (A = K, Rb).
