LaMnO3 is Orthorhombic Perovskite structured and crystallizes in the monoclinic P2_1/c space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 28-29°. In the second Mn site, Mn(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 28-29°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent La(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent La(1), one Mn(1), and one Mn(2) atom.
