Synthesis and Characteristics of a New Molybdoantimonate KSbMoO_5

摘要

A two-dimensional solid of KSbMoO_5 has been synthesized by hydrothermal methods and structurally characterized by X-ray crystallography. It crystallizes in the monoclinic system, space group P2_1/c with a = 9.2084(7), b = 11.3155(7), c = 5.6691(3) A, β = 107.624(3)°, V = 562.98(6) A~3, Z = 4, M_r = 336.79, D_c= 3.974 g/cm~3, F(000) = 608 and μ(MoKα) = 7.697 mm~(-1). The final R = 0.0496 and wR = 0.1294 for 888 observed reflections with I > 2σ(I). The structure is built up of SbMoO_5-layers, between every two of which sodium cations are located.
