Materials Data on Sr(FeS2)2 by Materials Project
Sr(FeS2)2 crystallizes in the tetragonal I422 space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. All Sr–S bond lengths are 3.13 Å. Fe3+ is bonded to four equivalent S2- atoms to form edge-sharing FeS4 tetrahedra. All Fe–S bond lengths are 2.15 Å. S2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two equivalent Fe3+ atoms.
