摘要：

The ab initio structure determination of Zr-2(WO4)(PO4)(2) from room temperature powder X-ray diffraction data is reported. This compound crystallizes in the orthorhombic space group Pnca with a = 9.35451(9), b = 12.31831(9), and c = 9.16711(8) Angstrom. The structure is based on ZrO6 octahedra sharing corners with WO4 and PO4 tetrahedra. Although Zr-2(WO4)(PO4)(2) is isostructural with Fe-2(MoO4)(3) and its WO4 and PO4 tetrahedra are well ordered, no superstructure or change in space group is required to account for this ordering.
