V2PbP4O14 crystallizes in the triclinic P-1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form VO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. In the second V site, V(2) is bonded to two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms to form VO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. Pb(1) is bonded in a distorted square co-planar geometry to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(4), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one V(2)O6 octahedra, corners with two equivalent V(1)O6 octahedra, and  a cornercorner with one P(2)O4 tetrahedra.
