VW2Pb crystallizes in the triclinic P1 space group. V(1) is bonded in a 3-coordinate geometry to two equivalent W(1), two equivalent W(2), and one Pb(1) atom. There is one shorter (2.53 Å) and one longer (2.99 Å) V(1)-W(1) bond length. There is one shorter (1.58 Å) and one longer (2.34 Å) V(1)-W(2) bond length. The V(1)-Pb(1) bond length is 2.11 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 5-coordinate geometry to two equivalent V(1), one W(2), and two equivalent Pb(1) atoms. The W(1)-W(2) bond length is 1.72 Å. There is one shorter (1.93 Å) and one longer (2.70 Å) W(1)-Pb(1) bond length. In the second W site, W(2) is bonded in a 4-coordinate geometry to two equivalent V(1), one W(1), and one Pb(1) atom. The W(2)-Pb(1) bond length is 2.08 Å. Pb(1) is bonded in a 1-coordinate geometry to one V(1), one W(2), and two equivalent W(1) atoms.
