The structure described by LaCoO3 is Orthorhombic Perovskite-like structured and crystallizes in the triclinic P-1 space group. La(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 20-21°. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 20-21°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent La(1), one Co(1), and one Co(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent La(1), one Co(1), and one Co(2) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent La(1), one Co(1), and one Co(2) atom. is represented by the CIF file [CIF]
