In the first Ce3+ site, Ce3+ is bonded in a 10-coordinate geometry to nine O2- and one F1- atom. There are a spread of Ce–O bond distances ranging from 2.48–2.69 Å. The Ce–F bond length is 2.36 Å. In the second Ce3+ site, Ce3+ is bonded in a 10-coordinate geometry to nine O2- and one F1- atom. There are a spread of Ce–O bond distances ranging from 2.50–2.75 Å. The Ce–F bond length is 2.39 Å. There are five inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.30 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. In the fourth C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.31 Å) C–O bond length. In the fifth C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two Ba2+, one Ce3+, and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Ce3+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, two equivalent Ce3+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Ba2+, two Ce3+, and one C4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one C4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two Ba2+, one Ce3+, and one C4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two Ba2+, one Ce3+, and one C4+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Ce3+, and one C4+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Ce3+, and one C4+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, two equivalent Ce3+, and one C4+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to three Ba2+ and one Ce3+ atom. In the second F1- site, F1- is bonded in a 1-coordinate geometry to three Ba2+ and one Ce3+ atom.
