LaMnO3 crystallizes in the orthorhombic Pnma 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 1-24°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent La(1) and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing OLa4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. 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.
LaMnO3 crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 12-coordinate geometry to four equivalent O(1) and eight equivalent O(2) atoms. There are a spread of La(1)-O(1) bond distances ranging from 2.72-2.84 Å. There are a spread of La(1)-O(2) bond distances ranging from 2.53-3.15 Å. 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 1-24°.
