The structure described by Fe5O7 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of edge and corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 14°. In the second Fe site, Fe(2) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 14°. In the third Fe site, Fe(3) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 120 degrees geometry to two equivalent Fe(3) atoms. In the second O site, O(1) is bonded to two equivalent Fe(2) and three equivalent Fe(1) atoms to form a mixture of edge and corner-sharing OFe5 square pyramids. In the third O site, O(2) is bonded in a trigonal non-coplanar geometry to one Fe(1) and two equivalent Fe(3) atoms. In the fourth O site, O(3) is bonded to one Fe(2), two equivalent Fe(1), and two equivalent Fe(3) atoms to form a mixture of edge and corner-sharing OFe5 square pyramids. is represented by the CIF card [CIF]
