LaMnO3 crystallizes in the tetragonal P4/mbm space group. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four 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 0-24°. 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 two equivalent La(1) and two equivalent Mn(1) atoms.
