La Sb Sb Pb
LaPbSb2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaPbSb2 clusters. La(1) is bonded in a linear geometry to one Pb(1) and one Sb(1) atom. The La(1)-Pb(1) bond length is 3.00 Å. The La(1)-Sb(1) bond length is 2.72 Å. Pb(1) is bonded in a single-bond geometry to one La(1) atom. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted linear geometry to one La(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 0.24 Å. In the second Sb site, Sb(2) is bonded in a single-bond geometry to one Sb(1) atom.
