The single-phase compound ..beta..-Zr/sub 2/(PO/sub 4/)/sub 2/SO/sub 4/ has been prepared by refluxing zirconium phosphate gel in sulfuric acid at 200/sup 0/C. It crystallizes in the orthorhombic system, space group Pbcn with a = 12.3742(9), b = 8.867(2), c = 8.951(1) A, Z = 4. The structure was determined from 560 reflections collected on a Nonius CAD4 automatic diffractometer with MoK/sub alpha/ radiation. The final R index and weighted R/sub w/ index are 0.049 and 0.062 respectively. The structure, built up from ZrO/sub 6/ octahedra and PO/sub 4/ and SO/sub 4/ tetrahedra linked by corners, is isotypic with that of Sc/sub 2/(WO/sub 4/)/sub 3/ and is closely related to that of garnet and nasicon. In these three structure types the arrangements of octahedral cations are very similar.
