In the fourth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.47–1.52 Å. In the fifth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.53 Å. In the sixth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.52 Å. There are fifteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three B3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Sm3+ and two equivalent B3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sm3+ and two B3+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sm3+ and two equivalent B3+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Sm3+ and two B3+ atoms.
