摘要：

Zirconium tungstate, Zr(WO4)(2), has been prepared by solid-state reaction at 1473 K. The structure was determined from X-ray acid neutron powder diffraction data and refined by the Rietveld method. The final R indices are R(F) = 0.032, R(I) = 0.027 and R(P) = 0.065. The structure contains WO4 tetrahedra, each linked by three corners to three ZrO6 octahedra; each tetrahedron has a terminal O atom with a short W-O distance. This arrangement is closely related to that of the Zr(MoO4)(2) high-temperature form.
