In Hg Pb
HgInPb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HgInPb clusters. Hg(1) is bonded in a single-bond geometry to one Pb(1) atom. The Hg(1)-Pb(1) bond length is 1.56 Å. In(1) is bonded in a single-bond geometry to one Pb(1) atom. The In(1)-Pb(1) bond length is 1.45 Å. Pb(1) is bonded in a linear geometry to one Hg(1) and one In(1) atom.
