The structure described by LaSrCrO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 9-coordinate geometry to one O(1), four equivalent O(2), and four equivalent O(3) atoms. La(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. Cr(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Sr(1), four equivalent La(1), and one Cr(1) atom to form distorted OSrLa4Cr octahedra that share  a cornercorner with one O(2)Sr4LaCr octahedra, corners with four equivalent O(1)SrLa4Cr octahedra, corners with twelve equivalent O(3)Sr2La2Cr2 octahedra, edges with four equivalent O(2)Sr4LaCr octahedra, edges with four equivalent O(1)SrLa4Cr octahedra, and faces with four equivalent O(3)Sr2La2Cr2 octahedra. The corner-sharing octahedral tilt angles range from 0-53°. In the second O site, O(2) is bonded to four equivalent Sr(1), one La(1), and one Cr(1) atom to form distorted OSr4LaCr octahedra that share  a cornercorner with one O(1)SrLa4Cr octahedra, corners with four equivalent O(2)Sr4LaCr octahedra, corners with twelve equivalent O(3)Sr2La2Cr2 octahedra, edges with four equivalent O(2)Sr4LaCr octahedra, edges with four equivalent O(1)SrLa4Cr octahedra, and faces with four equivalent O(3)Sr2La2Cr2 octahedra. The corner-sharing octahedral tilt angles range from 0-53°. In the third O site, O(3) is bonded to two equivalent Sr(1), two equivalent La(1), and two equivalent Cr(1) atoms to form distorted OSr2La2Cr2 octahedra that share corners with two equivalent O(3)Sr2La2Cr2 octahedra, corners with six equivalent O(2)Sr4LaCr octahedra, corners with six equivalent O(1)SrLa4Cr octahedra, edges with two equivalent O(3)Sr2La2Cr2 octahedra, faces with two equivalent O(2)Sr4LaCr octahedra, faces with two equivalent O(1)SrLa4Cr octahedra, and faces with four equivalent O(3)Sr2La2Cr2 octahedra. The corner-sharing octahedral tilt angles range from 6-53°. is represented by the CIF file [CIF]
