Four new lead phosphates, APbBi(PO)(PO) (A = Rb, Cs) and APbPO (A = K, Rb), have been synthesized by the high-temperature solution method. APbBi(PO)(PO) (A = Rb, Cs) compounds are isomorphic and crystallize into the space group of with different P-O groups, PO and PO. RbPbBi(PO)(PO) exhibits an interesting structure that can be regarded as the stacking of RbPb(PO) and BiPO. APbPO (A = K, Rb) compounds crystallize into the same space group of 2, but they are not isomorphic and exhibit different Pb-P-O frameworks. The influence of cation on the anion framework of APbPO (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 APbBi(PO)(PO) (A = Rb, Cs) and APbPO (A = K, Rb).
通过高温溶液法合成了四种新型铅磷酸盐，APbBi(PO)(PO)（A = Rb，Cs）和APbPO（A = K，Rb）。APbBi(PO)(PO)（A = Rb，Cs）化合物是同构的，结晶成具有不同P - O基团PO和PO的空间群。RbPbBi(PO)(PO)呈现出一种有趣的结构，可视为RbPb(PO)和BiPO的堆叠。APbPO（A = K，Rb）化合物结晶成相同的2空间群，但它们不是同构的，并且呈现出不同的Pb - P - O骨架。讨论了阳离子对APbPO（A = K，Rb）阴离子骨架的影响。这四种化合物均完全熔融。此外，我们还研究了阳离子对APbBi(PO)(PO)（A = Rb，Cs）和APbPO（A = K，Rb）热性能和光学性能的影响。
