摘要：

A ternary salt system Rb2MoO4-Ce-2(MoO4)(3)-Zr(MoO4)(2) is studied by powder XRD. Single crystals of 5:1:2 ternary rubidium-cerium-zirconium molybdate Rb5CeZr(MoO4)(6) are obtained by solution melt crystallization under spontaneous nucleation conditions. The crystal structure is solved by X-ray crystallography (X8 APEX automated diffractometer, MoK (alpha) radiation, 1274 F(hkl), R = 0.0456). The parameters of a trigonal unit cell are: a = b = 10.7248(2) , c = 38.796(1) , V = 3864.52(14) (3), Z = 6, space group. The three-dimensional complex framework comprises Mo tetrahedra linked to two independent (Ce,Zr)O-6 octahedra. Two types of rubidium atoms occupy large cavities of the framework.
