Actinide space group structure type

BRM(P04)3. CaAmPu(P04)3 has been synthesized recently and the monazite structure type has been attributed to it [81]. It is the only known compound among the BRM(P04)3 phosphates where tri- and tetravalent actinides are present together. Obviously, the Am and Pu" cations occupy cation sites with CN = 9 (monoclinic, space group P2 ln). The phosphate CaAmPu(P04)3 has an intermediate composition in the CaxAm3 2xPux(P04)3 series with x = 1. The first member of the row is AmP04 (x = 0) and the last one is Cai sPui 5(P04)3. CaPu(P04)2 (x = 1.5) has a monazite-type stmcture as well. [Pg.330]

The compositions of new phosphates with langbeinite structure type with 9-coordinated lanthanide ions have been proposed in [103, 104], The phosphates with composition Ai 5Lno,5[Fe2(P04)3] with A = K, Rb, Cs were s mthesized, and characterized by X-ray diffraction. The predicted cubic modification, space group P2i3 has been confirmed. This prediction seems to be promising for the actinide phosphate as well. [Pg.336]
