CdGaPb2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CdGaPb2 clusters. Cd(1) is bonded in a single-bond geometry to one Pb(1) atom. The Cd(1)-Pb(1) bond length is 0.26 Å. Ga(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Pb(2) atom. The Ga(1)-Pb(1) bond length is 1.88 Å. The Ga(1)-Pb(2) bond length is 1.17 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted single-bond geometry to one Cd(1) and one Ga(1) atom. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Ga(1) atom.
