The structure described by VZnPbO5 crystallizes in the orthorhombic Pnma space group. V(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form VO4 tetrahedra that share corners with four equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-59°. Zn(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) 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(2), one O(3), one O(4), and four equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one V(1), one Zn(1), and two equivalent Pb(1) atoms. 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 3-coordinate geometry to one V(1), two equivalent Zn(1), and one Pb(1) atom. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to two equivalent Zn(1) and one Pb(1) atom. is represented by the CIF card [CIF]
