The material structure described by SrFe2S2O crystallizes in the orthorhombic Pmn2_1 space group. Sr(1) is bonded in a distorted water-like geometry to three equivalent S(1), three equivalent S(2), and two equivalent O(1) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one S(2), two equivalent S(1), and one O(1) atom to form a mixture of distorted corner and edge-sharing FeS3O tetrahedra. In the second Fe site, Fe(2) is bonded to one S(1), two equivalent S(2), and one O(1) atom to form a mixture of distorted corner and edge-sharing FeS3O tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to three equivalent Sr(1), one Fe(2), and two equivalent Fe(1) atoms. In the second S site, S(2) is bonded in a 6-coordinate geometry to three equivalent Sr(1), one Fe(1), and two equivalent Fe(2) atoms. O(1) is bonded to two equivalent Sr(1), one Fe(1), and one Fe(2) atom to form corner-sharing OSr2Fe2 tetrahedra. is represented by the CIF card [CIF]
