The structure described by V2Zn3O7 crystallizes in the orthorhombic Cmc2_1 space group. V(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form VO6 octahedra that share corners with five equivalent V(1)O6 octahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with five equivalent Zn(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 40-43°. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form distorted ZnO4 tetrahedra that share corners with eight equivalent V(1)O6 octahedra and corners with two equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 65-84°. In the second Zn site, Zn(2) is bonded to one O(3) and three equivalent O(2) atoms to form distorted ZnO4 tetrahedra that share corners with five equivalent V(1)O6 octahedra and corners with six equivalent Zn(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 47-84°. There are four 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 and corners with two equivalent O(2)VZn3 tetrahedra. In the second O site, O(2) is bonded to one V(1) and three equivalent Zn(2) atoms to form OVZn3 tetrahedra that share  a cornercorner with one O(1)V2Zn2 tetrahedra and corners with six equivalent O(2)VZn3 tetrahedra. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Zn(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent V(1) and one Zn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
