VZnPbO5 crystallizes in the orthorhombic Pnma space group. V(1) is bonded to one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted VO5 trigonal bipyramids that share  a cornercorner with one Zn(1)O4 tetrahedra, corners with two equivalent V(1)O5 trigonal bipyramids, corners with four equivalent Pb(1)O4 trigonal pyramids, and  an edgeedge with one Zn(1)O4 tetrahedra. Zn(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form ZnO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra,  a cornercorner with one V(1)O5 trigonal bipyramid, and  an edgeedge with one V(1)O5 trigonal bipyramid. Pb(1) is bonded to four equivalent O(4) atoms to form distorted PbO4 trigonal pyramids that share corners with four equivalent V(1)O5 trigonal bipyramids and edges with two equivalent Pb(1)O4 trigonal pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a distorted water-like geometry to one V(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to two equivalent V(1) and one Zn(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one V(1) and two equivalent Pb(1) atoms.
