The structure described by LaCoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 12-coordinate geometry to four equivalent O(2) and eight equivalent O(1) atoms. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 20-24°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent La(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to four equivalent La(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
