SrUO4 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. U(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sr(1) and one U(1) atom to form distorted OSr3U tetrahedra that share corners with ten equivalent O(1)Sr3U tetrahedra, corners with six equivalent O(2)SrU3 trigonal pyramids, edges with three equivalent O(1)Sr3U tetrahedra, and edges with three equivalent O(2)SrU3 trigonal pyramids. In the second O site, O(2) is bonded to one Sr(1) and three equivalent U(1) atoms to form distorted OSrU3 trigonal pyramids that share corners with six equivalent O(1)Sr3U tetrahedra, corners with ten equivalent O(2)SrU3 trigonal pyramids, edges with three equivalent O(1)Sr3U tetrahedra, and edges with three equivalent O(2)SrU3 trigonal pyramids.
SrUO4 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Sr(1)-O(2) bond lengths are 2.70 Å. There are two shorter (2.43 Å) and four longer (2.52 Å) Sr(1)-O(1) bond lengths. U(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Both U(1)-O(1) bond lengths are 1.91 Å. There are four shorter (2.30 Å) and two longer (2.50 Å) U(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sr(1) and one U(1) atom to form distorted OSr3U tetrahedra that share corners with ten equivalent O(1)Sr3U tetrahedra, corners with six equivalent O(2)SrU3 trigonal pyramids, edges with three equivalent O(1)Sr3U tetrahedra, and edges with three equivalent O(2)SrU3 trigonal pyramids.
