description: CeB8O20Cl crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ce is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Ce–O bond distances ranging from 2.25–2.70 Å. There are eight 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 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 third 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 1.36–1.39 Å. In the fourth 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 1.36–1.40 Å. In the fifth B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra.
