Ge Ge Pb Cl
PbGe2Cl is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PbGe2Cl clusters. Pb(1) is bonded in a linear geometry to one Ge(2) and one Cl(1) atom. The Pb(1)-Ge(2) bond length is 1.52 Å. The Pb(1)-Cl(1) bond length is 1.31 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Cl(1) atom. The Ge(1)-Cl(1) bond length is 0.21 Å. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one Pb(1) atom. Cl(1) is bonded in a distorted linear geometry to one Pb(1) and one Ge(1) atom.
