SrFeO2 crystallizes in the tetragonal P4/mmm space group. Sr(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Fe(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent Sr(1) and two equivalent Fe(1) atoms to form a mixture of edge, corner, and face-sharing OSr4Fe2 octahedra. The corner-sharing octahedral tilt angles range from 0-64°.
