Abstract

Ba7B3GeO13Cl crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are six inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to seven O2- and two equivalent Cl1- atoms. There are a spread of Ba–O bond distances ranging from 2.63–3.06 Å. There are one shorter (3.11 Å) and one longer (3.27 Å) Ba–Cl bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 1-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.57–3.09 Å. In the third Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.66–3.06 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.70–3.01 Å. In the fifth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to seven O2- and one Cl1- atom. There are a spread of Ba–O bond distances ranging from 2.70–3.30 Å. The Ba–Cl bond length is 3.32 Å. In the sixth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.76–3.14 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.39 Å) and one longer (1.41 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. All B–O bond lengths are 1.39 Å. Ge4+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Ge–O bond distances ranging from 1.76–1.79 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to five Ba2+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four Ba2+ and one B3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four Ba2+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to four Ba2+ and one Ge4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one B3+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Ge4+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to four Ba2+ and one B3+ atom. Cl1- is bonded in a 4-coordinate geometry to four Ba2+ atoms.
