Ba3V4ZnO14 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.69–3.04 Å. In the second Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.68–2.93 Å. In the third Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.78–3.45 Å. There are four inequivalent V5+ sites. In the first 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 43°. There are a spread of V–O bond distances ranging from 1.71–1.83 Å. 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. There are a spread of Zn–O bond distances ranging from 2.01–2.64 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one V5+ atom.
