The material structure described by V2ZnO5 crystallizes in the orthorhombic Cmcm space group. V(1) is bonded to one O(1), one O(3), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent V(1) and two equivalent Zn(1) atoms to form OV2Zn2 tetrahedra that share corners with two equivalent O(1)V2Zn2 tetrahedra, corners with two equivalent O(2)V3Zn trigonal pyramids, and edges with four equivalent O(2)V3Zn trigonal pyramids. In the second O site, O(2) is bonded to three equivalent V(1) and one Zn(1) atom to form distorted OV3Zn trigonal pyramids that share  a cornercorner with one O(1)V2Zn2 tetrahedra, corners with three equivalent O(2)V3Zn trigonal pyramids, edges with two equivalent O(1)V2Zn2 tetrahedra, and edges with two equivalent O(2)V3Zn trigonal pyramids. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one Zn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
