KVPb2 crystallizes in the triclinic P1 space group. K(1) is bonded in a 1-coordinate geometry to one V(1), one Pb(1), and one Pb(2) atom. The K(1)-V(1) bond length is 1.79 Å. The K(1)-Pb(1) bond length is 4.01 Å. The K(1)-Pb(2) bond length is 2.81 Å. V(1) is bonded in a distorted single-bond geometry to one K(1) and one Pb(2) atom. The V(1)-Pb(2) bond length is 3.05 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to one K(1), one Pb(2), and two equivalent Pb(1) atoms. The Pb(1)-Pb(2) bond length is 2.23 Å. Both Pb(1)-Pb(1) bond lengths are 3.20 Å. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to one K(1), one V(1), and one Pb(1) atom.
