The structure described by LaSrCoO4 is (La,Ba)CuO4-derived structured and crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(1), three equivalent O(2), and four equivalent O(3) atoms. La(1) is bonded in a 9-coordinate geometry to two equivalent O(2), three equivalent O(1), and four equivalent O(3) atoms. Co(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), three equivalent La(1), and one Co(1) atom to form distorted OSr2La3Co octahedra that share  a cornercorner with one O(2)Sr3La2Co octahedra, corners with four equivalent O(1)Sr2La3Co octahedra, corners with twelve equivalent O(3)Sr2La2Co2 octahedra, edges with two equivalent O(1)Sr2La3Co octahedra, edges with six equivalent O(2)Sr3La2Co octahedra, and faces with four equivalent O(3)Sr2La2Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-53°. In the second O site, O(2) is bonded to three equivalent Sr(1), two equivalent La(1), and one Co(1) atom to form distorted OSr3La2Co octahedra that share  a cornercorner with one O(1)Sr2La3Co octahedra, corners with four equivalent O(2)Sr3La2Co octahedra, corners with twelve equivalent O(3)Sr2La2Co2 octahedra, edges with two equivalent O(2)Sr3La2Co octahedra, edges with six equivalent O(1)Sr2La3Co octahedra, and faces with four equivalent O(3)Sr2La2Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. In the third O site, O(3) 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(3)Sr2La2Co2 octahedra, corners with six equivalent O(1)Sr2La3Co octahedra, corners with six equivalent O(2)Sr3La2Co octahedra, edges with two equivalent O(3)Sr2La2Co2 octahedra, faces with two equivalent O(1)Sr2La3Co octahedra, faces with two equivalent O(2)Sr3La2Co octahedra, and faces with four equivalent O(3)Sr2La2Co2 octahedra. The corner-sharing octahedral tilt angles range from 1-55°. is represented by the CIF card [CIF]
