V2MnPb2O9 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent V sites. In the first V site, 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 two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 49°. In the second V site, V(2) is bonded to one O(4), one O(6), and two equivalent O(5) atoms to form VO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. Mn(1) is bonded to two equivalent O(3), two equivalent O(5), and two equivalent O(7) atoms to form MnO6 octahedra that share corners with two equivalent V(1)O4 tetrahedra, corners with two equivalent V(2)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one O(7) and two equivalent O(1) atoms. In the second Pb site, Pb(2) is bonded in a 4-coordinate geometry to one O(2), one O(4), and two equivalent O(1) atoms. There are seven inequivalent O sites.

In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mn(1) and one Pb(1) atom.
