The crystal structure described by SmBO3 crystallizes in the triclinic P-1 space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms. In the second Sm site, Sm(2) is bonded in a 8-coordinate geometry to one O(1), one O(3), one O(5), one O(6), two equivalent O(2), and two equivalent O(4) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(4) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(1), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one Sm(1), one Sm(2), and one B(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sm(1), two equivalent Sm(2), and one B(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sm(1), one Sm(2), and one B(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Sm(1), two equivalent Sm(2), and one B(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Sm(2), two equivalent Sm(1), and one B(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Sm(2), two equivalent Sm(1), and one B(2) atom. is represented by the CIF file [CIF]
