The material described by Ba2Fe2S2OF2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 9-coordinate geometry to four equivalent S(1), one O(1), and four equivalent F(1) atoms. Fe(1) is bonded in a distorted linear geometry to four equivalent S(1) and two equivalent O(1) atoms. S(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Fe(1) atoms. O(1) is bonded in a distorted square co-planar geometry to two equivalent Ba(1) and four equivalent Fe(1) atoms. F(1) is bonded to four equivalent Ba(1) atoms to form a mixture of edge and corner-sharing FBa4 tetrahedra. is represented by the CIF card [CIF]
