SmAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 12-coordinate geometry to four equivalent O(2) and eight equivalent O(1) atoms. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles range from 20-21°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent Sm(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to four equivalent Sm(1) and two equivalent Al(1) atoms.
SmAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 12-coordinate geometry to four equivalent O(2) and eight equivalent O(1) atoms. There are a spread of Sm(1)-O(2) bond distances ranging from 2.34-2.96 Å. There are a spread of Sm(1)-O(1) bond distances ranging from 2.37-3.06 Å. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles range from 20-21°. Both Al(1)-O(2) bond lengths are 1.90 Å. There are two shorter (1.89 Å) and two longer (1.90 Å) Al(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 four equivalent Sm(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to four equivalent Sm(1) and two equivalent Al(1) atoms.
