PbSbCl2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PbSbCl2 clusters. Pb(1) is bonded in a distorted linear geometry to one Sb(1) and one Cl(2) atom. The Pb(1)-Sb(1) bond length is 1.98 Å. The Pb(1)-Cl(2) bond length is 3.08 Å. Sb(1) is bonded in a distorted single-bond geometry to one Pb(1) and one Cl(1) atom. The Sb(1)-Cl(1) bond length is 1.11 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Sb(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Pb(1) atom.
