The material described by Sr(FeS2)2 crystallizes in the tetragonal I422 space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. Fe(1) is bonded to four equivalent S(1) atoms to form edge-sharing FeS4 tetrahedra. S(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
