Materials Data on V2ZnO4 by Materials Project

ZnV2O4 is Spinel structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six equivalent ZnO4 tetrahedra and edges with six VO6 octahedra. There are four shorter (2.04 Å) and two longer (2.10 Å) V–O bond lengths. In the second V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six equivalent ZnO4 tetrahedra and edges with six VO6 octahedra. There are a spread of V–O bond distances ranging from 2.03–2.07 Å. In the third V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six equivalent ZnO4 tetrahedra and edges with six VO6 octahedra. There are two shorter (2.03 Å) and four longer (2.07 Å) V–O bond lengths. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with twelve VO6 octahedra. The corner-sharing octahedra tilt angles range from 56–60°. There are one shorter (2.00 Å) and three longer (2.01 Å) Zn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three V3+ and one Zn2+ atom to form a mixture of distorted edge and corner-sharing OV3Zn trigonal pyramids. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to three V3+ and one Zn2+ atom. In the third O2- site, O2- is bonded in a rectangular see-saw-like geometry to three V3+ and one Zn2+ atom.
