LaMnO3 is Orthorhombic Perovskite-like structured and crystallizes in the monoclinic C2/c space group. La(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 19-22°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent La(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent La(1) and two equivalent Mn(1) atoms.
LaMnO3 is Orthorhombic Perovskite-like structured and crystallizes in the monoclinic C2/c space group. La(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.44 Å) and two longer (2.76 Å) La(1)-O(2) bond lengths. There are a spread of La(1)-O(1) bond distances ranging from 2.41-2.85 Å. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 19-22°. Both Mn(1)-O(2) bond lengths are 1.98 Å. There are two shorter (1.97 Å) and two longer (2.00 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 three equivalent La(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent La(1) and two equivalent Mn(1) atoms.
