Materials Data on Ba2CeC3O9F by Materials Project
Ba2CeC3O9F crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.70–3.04 Å. In the second Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to seven O2- and three equivalent F1- atoms. There are a spread of Ba–O bond distances ranging from 2.79–2.92 Å. There are one shorter (2.76 Å) and two longer (2.91 Å) Ba–F bond lengths. 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 2.42 Å. There are three 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 (1.31 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 (1.31 Å) C–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Ce3+, and one C4+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to two Ba2+, one Ce3+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Ce3+, and one C4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, two equivalent Ce3+, and one C4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Ce3+, and one C4+ atom. F1- is bonded to three equivalent Ba2+ and one Ce3+ atom to form a mixture of distorted edge and corner-sharing FBa3Ce tetrahedra.
