The material structure described by SmCoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 26-27°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sm(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sm(1) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
