The structure described by Sr3Fe2(O2Cl)2 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. Fe(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) and one Cl(1) atom. O(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Fe(1) atoms to form a mixture of corner, edge, and face-sharing OSr4Fe2 octahedra. The corner-sharing octahedral tilt angles range from 0-65°. Cl(1) is bonded in a distorted hexagonal planar geometry to five equivalent Sr(2) and one Fe(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
