PbGeCl2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PbGeCl2 cluster. Pb(1) is bonded in a distorted linear geometry to one Ge(1) and one Cl(1) atom. The Pb(1)-Ge(1) bond length is 1.15 Å. The Pb(1)-Cl(1) bond length is 1.95 Å. Ge(1) is bonded in a single-bond geometry to one Pb(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a water-like geometry to one Pb(1) and one Cl(2) atom. The Cl(1)-Cl(2) bond length is 0.71 Å. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Cl(1) atom.
