V3ZnO7 crystallizes in the orthorhombic Pnma space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(1), and two equivalent O(2) atoms. In the second V site, V(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. Zn(1) is bonded in a square pyramidal geometry to one O(3), two equivalent O(1), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a bent 120 degrees geometry to one V(2) and one Zn(1) atom. In the second O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one Zn(1) atom. In the third O site, O(1) is bonded to one V(2), two equivalent V(1), and one Zn(1) atom to form a mixture of distorted edge and corner-sharing OV3Zn tetrahedra. In the fourth O site, O(2) is bonded in a trigonal non-coplanar geometry to one V(2) and two equivalent V(1) atoms.

In the first V site, V(1) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(1), and two equivalent O(2) atoms. The V(1)-O(4) bond length is 1.68 Å. There is one shorter (2.01 Å) and one longer (2.03 Å) V(1)-O(1) bond length. There is one shorter (1.95 Å) and one longer (1.98 Å) V(1)-O(2) bond length. In the second V site, V(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. The V(2)-O(3) bond length is 1.67 Å.
