Abstract

SrIn2Se4 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are four shorter (3.29 Å) and four longer (3.36 Å) Sr–Se bond lengths. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are four shorter (3.27 Å) and four longer (3.38 Å) Sr–Se bond lengths. In the third Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Sr–Se bond distances ranging from 3.26–3.41 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four Se2- atoms to form a mixture of corner and edge-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 corner and edge-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 Sr2+ and two In3+more »« less
