The structure described by SrU2O6 is Fluorite-derived structured and crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. U(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Sr(1) and three equivalent U(1) atoms to form OSrU3 tetrahedra that share corners with six equivalent O(2)Sr2U2 tetrahedra, corners with ten equivalent O(1)SrU3 tetrahedra, edges with two equivalent O(2)Sr2U2 tetrahedra, and edges with four equivalent O(1)SrU3 tetrahedra. In the second O site, O(2) is bonded to two equivalent Sr(1) and two equivalent U(1) atoms to form OSr2U2 tetrahedra that share corners with four equivalent O(2)Sr2U2 tetrahedra, corners with twelve equivalent O(1)SrU3 tetrahedra, edges with two equivalent O(2)Sr2U2 tetrahedra, and edges with four equivalent O(1)SrU3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
