LaB7O15I crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La is bonded in a 1-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.24–2.78 Å. There are seven inequivalent B sites. In the first B site, B is bonded in a trigonal planar geometry to three O atoms. There is two shorter (1.37 Å) and one longer (1.38 Å) B–O bond length. In the second B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.43–1.54 Å. In the third B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.43–1.53 Å. In the fourth B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.43–1.52 Å. In the fifth B site, B is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.37 Å) and two longer (1.38 Å) B–O bond length. In the sixth B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.36–1.38 Å. In the seventh B site, B is bonded in a trigonal planar geometry to three O atoms. There is two shorter (1.37 Å) and one longer (1.38 Å) B–O bond length. There are fifteen inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one La and two B atoms. In the third O site, O is bonded in a distorted bent 120 degrees geometry to one La and two B atoms. In the fourth O site, O is bonded in a trigonal planar geometry to three B atoms. In the fifth O site, O is bonded in a bent 120 degrees geometry to one La and two B atoms. In the sixth O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the seventh O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the eighth O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the ninth O site, O is bonded in a distorted bent 120 degrees geometry to one La and two B atoms. In the tenth O site, O is bonded in a bent 120 degrees geometry to one O and one I atom. The O–O bond length is 1.31 Å. The O–I bond length is 2.15 Å. In the eleventh O site, O is bonded in a distorted bent 120 degrees geometry to one La and two B atoms. In the twelfth O site, O is bonded in a single-bond geometry to one La atom. In the thirteenth O site, O is bonded in a distorted bent 120 degrees geometry to one La and two B atoms. In the fourteenth O site, O is bonded in an L-shaped geometry to one La and one O atom. In the fifteenth O site, O is bonded in a single-bond geometry to one B atom. I is bonded in a single-bond geometry to one O atom.
