The compound described by ZnV2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with six equivalent V(2)O6 octahedra and corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-58°. In the second V site, V(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form VO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra, edges with two equivalent V(2)O6 octahedra, and edges with four equivalent Zn(1)O6 octahedra. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent V(2)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one V(1), one V(2), and two equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one V(1), two equivalent V(2), and one Zn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
