Materials Data on Ba2In2S5 by Materials Project

Abstract

Ba2In2S5 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first 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 3.19–3.84 Å. In the second Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.14–3.83 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four S2- atoms to form corner-sharing InS4 tetrahedra. There are a spread of In–S bond distances ranging from 2.43–2.55 Å. In the second In3+ site, In3+ is bonded to four S2- atoms to form corner-sharing InS4 tetrahedra. There are a spread of In–S bond distances ranging from 2.45–2.54 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinate geometry to three Ba2+ and two In3+ atoms. In the second S2- site, S2- is bonded to four Ba2+ and one In3+ atom to form a mixture of distorted edge and corner-sharing SBa4In trigonal bipyramids. In the third S2- site, S2- is bonded in a 4-coordinate geometry to two Ba2+ and two In3+ atoms. In the fourth S2- site, S2- is bonded to four Ba2+ and one In3+ atom to form a mixture of distorted edge and corner-sharing SBa4In trigonal bipyramids. In the fifth S2- site, S2- is bonded to three Ba2+ and two In3+ atoms to form a mixture of distorted edge and corner-sharing SBa3In2 trigonal bipyramids.
