Mg Mg In Pb
Mg2InPb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Mg2InPb cluster. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a bent 150 degrees geometry to one Mg(2) and one Pb(1) atom. The Mg(1)-Mg(2) bond length is 0.28 Å. The Mg(1)-Pb(1) bond length is 1.45 Å. In the second Mg site, Mg(2) is bonded in a bent 150 degrees geometry to one Mg(1) and one In(1) atom. The Mg(2)-In(1) bond length is 1.20 Å. In(1) is bonded in a distorted single-bond geometry to one Mg(2) atom. Pb(1) is bonded in a distorted single-bond geometry to one Mg(1) atom.
