Materials Data on Sr(FeS2)2 by Materials Project
Sr(FeS2)2 crystallizes in the orthorhombic Pban 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 S2- atoms. All Sr–S bond lengths are 3.13 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight S2- atoms. All Sr–S bond lengths are 3.13 Å. In the third Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight S2- atoms. All Sr–S bond lengths are 3.13 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to four S2- atoms to form edge-sharing FeS4 tetrahedra. There are one shorter (2.14 Å) and three longer (2.15 Å) Fe–S bond lengths. In the second Fe3+ site, Fe3+ is bonded to four S2- atoms to form edge-sharing FeS4 tetrahedra. There are three shorter (2.14 Å) and one longer (2.15 Å) Fe–S bond lengths. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to two Sr2+ and two Fe3+ atoms. In the second S2- site, S2- is bonded in a 4-coordinate geometry to two Sr2+ and two Fe3+ atoms. In the third S2- site, S2- is bonded in a 4-coordinate geometry to two Sr2+ and two Fe3+ atoms. In the fourth S2- site, S2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two Fe3+ atoms.
