The material structure described by SmAlO3 is Orthorhombic Perovskite-like 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 17-23°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Sm(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to four equivalent Sm(1) and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
