SmBO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sm–O bond distances ranging from 2.29–2.64 Å. In the second Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sm–O bond distances ranging from 2.29–2.66 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.41 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.41 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Sm3+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Sm3+ and one B3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Sm3+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Sm3+ and one B3+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Sm3+ and one B3+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Sm3+ and one B3+ atom.
