Li2InPb crystallizes in the trigonal R3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one Li(2), three equivalent In(1), and three equivalent Pb(1) atoms to form distorted edge-sharing LiLiIn3Pb3 hexagonal pyramids. The Li(1)-Li(2) bond length is 2.40 Å. All Li(1)-In(1) bond lengths are 3.02 Å. All Li(1)-Pb(1) bond lengths are 3.17 Å. In the second Li site, Li(2) is bonded in a 5-coordinate geometry to one Li(1), one In(1), and three equivalent Pb(1) atoms. The Li(2)-In(1) bond length is 2.40 Å. All Li(2)-Pb(1) bond lengths are 3.02 Å. In(1) is bonded in a 5-coordinate geometry to one Li(2), three equivalent Li(1), and one Pb(1) atom. The In(1)-Pb(1) bond length is 2.40 Å. Pb(1) is bonded in a 7-coordinate geometry to three equivalent Li(1), three equivalent Li(2), and one In(1) atom.
