The material structure described by LaSrCoO4 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(2), four equivalent O(1), and four equivalent O(3) atoms. La(1) is bonded in a 9-coordinate geometry to one O(3), four equivalent O(1), and four equivalent O(2) atoms. Co(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form corner-sharing CoO6 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 two equivalent Sr(1), two equivalent La(1), and two equivalent Co(1) atoms to form distorted OSr2La2Co2 octahedra that share corners with two equivalent O(1)Sr2La2Co2 octahedra, corners with six equivalent O(3)Sr4LaCo octahedra, corners with six equivalent O(2)SrLa4Co octahedra, edges with two equivalent O(1)Sr2La2Co2 octahedra, faces with two equivalent O(3)Sr4LaCo octahedra, faces with two equivalent O(2)SrLa4Co octahedra, and faces with four equivalent O(1)Sr2La2Co2 octahedra. The corner-sharing octahedral tilt angles range from 6-54°. In the second O site, O(2) is bonded to one Sr(1), four equivalent La(1), and one Co(1) atom to form distorted OSrLa4Co octahedra that share  a cornercorner with one O(3)Sr4LaCo octahedra, corners with four equivalent O(2)SrLa4Co octahedra, corners with twelve equivalent O(1)Sr2La2Co2 octahedra, edges with four equivalent O(3)Sr4LaCo octahedra, edges with four equivalent O(2)SrLa4Co octahedra, and faces with four equivalent O(1)Sr2La2Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-54°. In the third O site, O(3) is bonded to four equivalent Sr(1), one La(1), and one Co(1) atom to form distorted OSr4LaCo octahedra that share  a cornercorner with one O(2)SrLa4Co octahedra, corners with four equivalent O(3)Sr4LaCo octahedra, corners with twelve equivalent O(1)Sr2La2Co2 octahedra, edges with four equivalent O(3)Sr4LaCo octahedra, edges with four equivalent O(2)SrLa4Co octahedra, and faces with four equivalent O(1)Sr2La2Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-53°. is represented by the Crystallographic Information File (CIF) [CIF]
