In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one ZnO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of V–O bond distances ranging from 1.70–1.86 Å. In the third V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one ZnO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. There are a spread of V–O bond distances ranging from 1.69–1.84 Å. In the fourth V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three equivalent ZnO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–56°. There are a spread of V–O bond distances ranging from 1.68–1.86 Å. Zn2+ is bonded to six O2- atoms to form distorted ZnO6 octahedra that share corners with six VO4 tetrahedra and an edgeedge with one ZnO6 octahedra.
