Li Ir Ir Pb
LiIr2Pb crystallizes in the triclinic P1 space group. Li(1) is bonded in a single-bond geometry to one Ir(1) and two equivalent Pb(1) atoms. The Li(1)-Ir(1) bond length is 0.82 Å. There is one shorter (2.71 Å) and one longer (3.33 Å) Li(1)-Pb(1) bond length. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one Li(1) and one Pb(1) atom. The Ir(1)-Pb(1) bond length is 2.76 Å. In the second Ir site, Ir(2) is bonded in a 1-coordinate geometry to two equivalent Pb(1) atoms. There is one shorter (2.39 Å) and one longer (3.11 Å) Ir(2)-Pb(1) bond length. Pb(1) is bonded in a 7-coordinate geometry to two equivalent Li(1), one Ir(1), two equivalent Ir(2), and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 2.97 Å.
