Sr2UO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent O(1) and five equivalent O(2) atoms. U(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted linear geometry to five equivalent Sr(1) and one U(1) atom. In the second O site, O(1) is bonded to four equivalent Sr(1) and two equivalent U(1) atoms to form a mixture of distorted corner, edge, and face-sharing OSr4U2 octahedra. The corner-sharing octahedra are not tilted.
Sr2UO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent O(1) and five equivalent O(2) atoms. All Sr(1)-O(1) bond lengths are 2.92 Å. There is one shorter (2.35 Å) and four longer (3.14 Å) Sr(1)-O(2) bond lengths. U(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedra are not tilted. Both U(1)-O(2) bond lengths are 2.19 Å. All U(1)-O(1) bond lengths are 2.21 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted linear geometry to five equivalent Sr(1) and one U(1) atom. In the second O site, O(1) is bonded to four equivalent Sr(1) and two equivalent U(1) atoms to form a mixture of distorted corner, edge, and face-sharing OSr4U2 octahedra.
