Abstract

Ba4Cu2Al3F21 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Ba–F bond distances ranging from 2.70–3.23 Å. In the second Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Ba–F bond distances ranging from 2.66–3.14 Å. In the third Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Ba–F bond distances ranging from 2.68–3.09 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve F1- atoms. There are a spread of Ba–F bond distances ranging from 2.78–3.27 Å. There are two inequivalent Cu2+ sites.

In the seventeenth F1- site, F1- is bonded in a distorted single-bond geometry to three Ba2+ and one Al3+ atom. In the eighteenth F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one Al3+ atom. In the nineteenth F1- site, F1- is bonded in a distorted water-like geometry to two Ba2+ and two Cu2+ atoms.
