FeZnO2F5 crystallizes in the orthorhombic Imma space group. Fe(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form FeF6 octahedra that share corners with two equivalent Fe(1)F6 octahedra and corners with four equivalent Zn(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 39-41°. Zn(1) is bonded to two equivalent O(1) and four equivalent F(2) atoms to form ZnO2F4 octahedra that share corners with four equivalent Fe(1)F6 octahedra. The corner-sharing octahedral tilt angles are 41°. O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one O(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Fe(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Fe(1) and one Zn(1) atom.
