Crystal data for antimony molybdenum oxide Sb2MoO6

The powder data for antimony molybdenum oxide Sb2MoO6 are reported. This compound is triclinic, P{\bar 1}, with a = 7.481(4), b = 7.504(3), c = 10.120(1) A, α = 70.43(3), β = 70.91(4), γ = 83.34(7)°; U = 505.9(5) A3; Z = 4; Dx = 5.74 Mg m−3. The structure is of the fluorite type but it is distorted. Pseudo-monoclinic cells as reported by Parmentier, Courtois & Gleitzer [Bull. Soc. Chim. Ft. (1974), 1–2, 75–77] or that obtained with program TRACER [Lawton & Jacobson (1965). Mobil Oil Corporation Research Department; Lawton (1967). Mobil Oil Corporation Research Department] are also considered and discussed. Neutron diffraction gives further evidence of the triclinic lattice. The JCPDS Diffraction File No. for Sb2MoO6 is 33–1491.
