VZnBiO5 crystallizes in the monoclinic P2_1/c space group. V(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form VO4 tetrahedra that share corners with four equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-49°. Zn(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form ZnO6 octahedra that share corners with four equivalent V(1)O4 tetrahedra and  an edgeedge with one Zn(1)O6 octahedra. Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one V(1), one Zn(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one V(1), one Zn(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one V(1), one Zn(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded to two equivalent Zn(1) and two equivalent Bi(1) atoms to form edge-sharing OZn2Bi2 tetrahedra. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one V(1), one Zn(1), and one Bi(1) atom.
