LaCrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent La(1) and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Cr(1) atoms.
LaCrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.40 Å) and one longer (2.56 Å) La(1)-O(2) bond length. There are a spread of La(1)-O(1) bond distances ranging from 2.43-2.77 Å. Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 23°. Both Cr(1)-O(2) bond lengths are 1.99 Å. All Cr(1)-O(1) bond lengths are 1.99 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent La(1) and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Cr(1) atoms.
