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.
