The material structure described by SmBO3 crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Sm(1) and one B(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Sm(1) and one B(1) atom. is represented by the CIF file [CIF]
