Materials Data on Ba(InSe2)2 by Materials Project
BaIn2Se4 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Ba–Se bond distances ranging from 3.41–3.50 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are four shorter (3.42 Å) and four longer (3.48 Å) Ba–Se bond lengths. In the third Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are four shorter (3.43 Å) and four longer (3.47 Å) Ba–Se bond lengths. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four Se2- atoms to form a mixture of edge and corner-sharing InSe4 tetrahedra. There are a spread of In–Se bond distances ranging from 2.59–2.66 Å. In the second In3+ site, In3+ is bonded to four Se2- atoms to form a mixture of edge and corner-sharing InSe4 tetrahedra. There are a spread of In–Se bond distances ranging from 2.59–2.66 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to two Ba2+ and two In3+ atoms to form a mixture of distorted edge and corner-sharing SeBa2In2 trigonal pyramids. In the second Se2- site, Se2- is bonded to two Ba2+ and two In3+ atoms to form a mixture of distorted edge and corner-sharing SeBa2In2 trigonal pyramids. In the third Se2- site, Se2- is bonded in a 4-coordinate geometry to two Ba2+ and two equivalent In3+ atoms. In the fourth Se2- site, Se2- is bonded in a 4-coordinate geometry to two Ba2+ and two equivalent In3+ atoms.
