LuErO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Lu(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 45-48°. Er(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Lu(1) and two equivalent Er(1) atoms to form distorted corner-sharing OEr2Lu2 trigonal pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Lu(1) and three equivalent Er(1) atoms.
LuErO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Lu(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 45-48°. Both Lu(1)-O(1) bond lengths are 2.25 Å. There are two shorter (2.18 Å) and two longer (2.19 Å) Lu(1)-O(2) bond lengths. Er(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There is one shorter (2.20 Å) and one longer (2.35 Å) Er(1)-O(1) bond length. There are a spread of Er(1)-O(2) bond distances ranging from 2.20-2.97 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Lu(1) and two equivalent Er(1) atoms to form distorted corner-sharing OEr2Lu2 trigonal pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Lu(1) and three equivalent Er(1) atoms.
