摘要：

Single crystals of Pb-3[(PO4)(2)BPO4] were obtained by melting B2O3, P2O5 and PbO at 960 degrees C. The structure is related to the Ba-3[(PO4)(2)BPO4] type X-ray investigations on single crystals led to the space group Pbca-D-2h(15) (Nr. 61) with a = 694.6(1), b = 1419.9(3), c = 2111.6(2) pm, Z = 8. Boron and phosphorus are tetrahedrally coordinated by oxygen. The polyhedra form one-dimensional infinite helices that contain two additional PQ(4) groups connected to the BO4-unit. Lead is eightfold coordinated by oxygen. The relation to the crystal structure of Ba-3[(PO4)(2)BPO4] is discussed.
