Fe2V4O13 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with two equivalent FeO6 octahedra and corners with two VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 26–33°. There are a spread of V–O bond distances ranging from 1.69–1.79 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with two equivalent FeO6 octahedra and corners with two VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 19–45°. There are a spread of V–O bond distances ranging from 1.69–1.80 Å. In the third V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four FeO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 5–54°. There are a spread of V–O bond distances ranging from 1.69–1.81 Å. In the fourth V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four FeO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 14–57°. There are a spread of V–O bond distances ranging from 1.70–1.81 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six VO4 tetrahedra and an edgeedge with one FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.99–2.08 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six VO4 tetrahedra and an edgeedge with one FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.99–2.09 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two V5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V5+ and one Fe3+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one V5+ and two Fe3+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to one V5+ and one Fe3+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one V5+ and two Fe3+ atoms. In the sixth O2- site, O2- is bonded in a linear geometry to one V5+ and one Fe3+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Fe3+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Fe3+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Fe3+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Fe3+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to two V5+ atoms. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V5+ and one Fe3+ atom. In the thirteenth O2- site, O2- is bonded in a bent 150 degrees geometry to two V5+ atoms.
