La2B8O15 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. La3+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of La–O bond distances ranging from 2.33–2.95 Å. There are four inequivalent B3+ sites. In the first 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 1.43–1.57 Å. In the second 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 1.44–1.54 Å. In the third 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 1.42–1.55 Å. 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 1.45–1.52 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent La3+ and two B3+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent La3+ and two B3+ atoms. In the third O2- site, O2- is bonded in a trigonal planar geometry to three B3+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two B3+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent La3+ and two equivalent B3+ atoms. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent La3+ and one B3+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent La3+ and two B3+ atoms. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to three B3+ atoms.
