The crystal structure described by SrUO4 crystallizes in the orthorhombic Pbcm space group. Sr(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent O(3) atoms. U(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedral tilt angles range from 42-50°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Sr(1) and two equivalent U(1) atoms. In the second O site, O(2) is bonded to two equivalent Sr(1) and two equivalent U(1) atoms to form distorted corner-sharing OSr2U2 tetrahedra. In the third O site, O(3) is bonded in a 1-coordinate geometry to two equivalent Sr(1) and one U(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
