HgIn2Pb crystallizes in the triclinic P1 space group. Hg(1) is bonded in a 5-coordinate geometry to one In(1), three equivalent In(2), and one Pb(1) atom. The Hg(1)-In(1) bond length is 3.32 Å. There are a spread of Hg(1)-In(2) bond distances ranging from 2.33-3.26 Å. The Hg(1)-Pb(1) bond length is 2.60 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted single-bond geometry to one Hg(1) and one Pb(1) atom. The In(1)-Pb(1) bond length is 2.65 Å. In the second In site, In(2) is bonded in a 2-coordinate geometry to three equivalent Hg(1) and one Pb(1) atom. The In(2)-Pb(1) bond length is 2.65 Å. Pb(1) is bonded in a 3-coordinate geometry to one Hg(1), one In(1), and one In(2) atom.
