The structure described by LaMnO3 crystallizes in the orthorhombic Pbam space group. La(1) is bonded in a 12-coordinate geometry to four equivalent O(1) and eight equivalent O(2) atoms. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 0-26°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent La(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to four equivalent La(1) and two equivalent Mn(1) atoms. is represented by the CIF file [CIF]
