The material described by La2O2Fe2OS2 crystallizes in the tetragonal I4/mmm space group. La(1) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. Fe(1) is bonded in a distorted linear geometry to four equivalent S(1) and two equivalent O(2) atoms. S(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Fe(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra. In the second O site, O(2) is bonded in a square co-planar geometry to four equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
