ErScO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Er(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. Sc(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles range from 41-44°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Er(1) and two equivalent Sc(1) atoms. In the second O site, O(2) is bonded to two equivalent Er(1) and two equivalent Sc(1) atoms to form distorted corner-sharing OEr2Sc2 trigonal pyramids.
ErScO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Er(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.20 Å) and one longer (2.31 Å) Er(1)-O(2) bond length. There are a spread of Er(1)-O(1) bond distances ranging from 2.23-2.85 Å. Sc(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles range from 41-44°. Both Sc(1)-O(2) bond lengths are 2.14 Å. There are two shorter (2.09 Å) and two longer (2.12 Å) Sc(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Er(1) and two equivalent Sc(1) atoms. In the second O site, O(2) is bonded to two equivalent Er(1) and two equivalent Sc(1) atoms to form distorted corner-sharing OEr2Sc2 trigonal pyramids.
