Rietveld refinement of the crystal structure of γ-mo_4O_11

摘要

The crystal structure of γ-Mo_4O_11 was obtained at room temperature (296 k) by Rietveld analysis with X-ray powder diffraction data. The crystal belongs to orthorhombic system, space group: pna2_1, z=4, Mr=559.753 (Atomic weights 1977), D_x=4.1228 g/cm~3, F(ooo)=1024.o, μ=451.293 cm~-1 (Int. Tab. Vol. C, Table 4.2.4.2, p. 193, λ=1.540 60 A), a=24.4756(5) A, b=6.7516(1) A, c=5.4572(1) A, and V=901.80(3) A~3.
