LaMnO3 crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 5-coordinate geometry to two equivalent O(1) and three equivalent O(2) atoms. Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one La(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to three equivalent La(1) atoms.
LaMnO3 crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 5-coordinate geometry to two equivalent O(1) and three equivalent O(2) atoms. Both La(1)-O(1) bond lengths are 2.48 Å. There are a spread of La(1)-O(2) bond distances ranging from 2.15-2.36 Å. Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two shorter (1.99 Å) and two longer (2.02 Å) Mn(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one La(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to three equivalent La(1) atoms.
