Materials Data on Ba2GdC2(O2F)3 by Materials Project

Abstract

Ba2GdC2(O2F)3 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to five O2- and four F1- atoms. There are a spread of Ba–O bond distances ranging from 2.80–2.92 Å. There are a spread of Ba–F bond distances ranging from 2.61–2.86 Å. Gd3+ is bonded in a 9-coordinate geometry to six O2- and three F1- atoms. There are a spread of Gd–O bond distances ranging from 2.46–2.58 Å. There are two shorter (2.34 Å) and one longer (2.35 Å) Gd–F bond lengths. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.28 Å) and two longer (1.31 Å) C–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Gd3+, and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, one Gd3+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Gd3+, and one C4+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to two equivalent Ba2+ and one Gd3+ atom. In the second F1- site, F1- is bonded in a 4-coordinate geometry to three equivalent Ba2+ and one Gd3+ atom.
