VZnPbO5 crystallizes in the orthorhombic P2_12_12_1 space group. V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share corners with four equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-60°. Zn(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(5) atoms to form ZnO6 octahedra that share corners with four equivalent V(1)O4 tetrahedra and edges with two equivalent Zn(1)O6 octahedra. Pb(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(5), two equivalent O(3), 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), two equivalent Zn(1), and one Pb(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one V(1) and one Pb(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one V(1), one Zn(1), and two equivalent Pb(1) atoms. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one V(1), one Zn(1), and two equivalent Pb(1) atoms. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to two equivalent Zn(1) and one Pb(1) atom.
