V2PbGe crystallizes in the monoclinic Cm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 9-coordinate geometry to four equivalent V(1), four equivalent V(2), and one Ge(1) atom. All V(1)-V(1) bond lengths are 3.22 Å. There are a spread of V(1)-V(2) bond distances ranging from 2.43-3.22 Å. The V(1)-Ge(1) bond length is 3.19 Å. In the second V site, V(2) is bonded in a single-bond geometry to four equivalent V(1) and one Pb(1) atom. The V(2)-Pb(1) bond length is 1.58 Å. Pb(1) is bonded in a 1-coordinate geometry to one V(2) and four equivalent Ge(1) atoms. There are a spread of Pb(1)-Ge(1) bond distances ranging from 2.03-2.93 Å. Ge(1) is bonded in a 5-coordinate geometry to one V(1) and four equivalent Pb(1) atoms.
