The structure described by SrU2S5 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded to one S(1), one S(2), one S(3), and four equivalent S(4) atoms to form distorted edge-sharing SrS7 pentagonal bipyramids. U(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded to one Sr(1) and four equivalent U(1) atoms to form SSrU4 square pyramids that share corners with four equivalent S(1)SrU4 square pyramids, corners with four equivalent S(3)SrU4 square pyramids, corners with four equivalent S(4)Sr2U2 tetrahedra,  a cornercorner with one S(2)SrU4 trigonal bipyramid,  an edgeedge with one S(3)SrU4 square pyramid, edges with four equivalent S(4)Sr2U2 tetrahedra, edges with four equivalent S(2)SrU4 trigonal bipyramids, and  a faceface with one S(3)SrU4 square pyramid. In the second S site, S(2) is bonded to one Sr(1) and four equivalent U(1) atoms to form distorted SSrU4 trigonal bipyramids that share  a cornercorner with one S(1)SrU4 square pyramid, corners with five equivalent S(3)SrU4 square pyramids, corners with four equivalent S(4)Sr2U2 tetrahedra, corners with four equivalent S(2)SrU4 trigonal bipyramids, edges with two equivalent S(3)SrU4 square pyramids, edges with four equivalent S(1)SrU4 square pyramids, and edges with four equivalent S(4)Sr2U2 tetrahedra. In the third S site, S(3) is bonded to one Sr(1) and four equivalent U(1) atoms to form SSrU4 square pyramids that share corners with four equivalent S(1)SrU4 square pyramids, corners with eight equivalent S(4)Sr2U2 tetrahedra, corners with five equivalent S(2)SrU4 trigonal bipyramids,  an edgeedge with one S(1)SrU4 square pyramid, edges with two equivalent S(3)SrU4 square pyramids, edges with two equivalent S(4)Sr2U2 tetrahedra, edges with two equivalent S(2)SrU4 trigonal bipyramids, and  a faceface with one S(1)SrU4 square pyramid.
