Materials Data on Ba5(GaS4)2 by Materials Project
Ba5(GaS4)2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of Ba–S bond distances ranging from 3.49–3.68 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.12–3.70 Å. In the third Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.02–3.76 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded in a tetrahedral geometry to four S2- atoms. There are two shorter (2.28 Å) and two longer (2.30 Å) Ga–S bond lengths. In the second Ga3+ site, Ga3+ is bonded in a tetrahedral geometry to four S2- atoms. There are a spread of Ga–S bond distances ranging from 2.27–2.37 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to five Ba2+ and one Ga3+ atom. In the second S2- site, S2- is bonded in a 1-coordinate geometry to six Ba2+ and one Ga3+ atom. In the third S2- site, S2- is bonded in a 6-coordinate geometry to five Ba2+ and one Ga3+ atom. In the fourth S2- site, S2- is bonded in a 1-coordinate geometry to six Ba2+ and one Ga3+ atom. In the fifth S2- site, S2- is bonded in a 6-coordinate geometry to five Ba2+ and one Ga3+ atom.
