Al Ga Ga Pb
Ga2AlPb crystallizes in the triclinic P1 space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to two equivalent Ga(2) and two equivalent Pb(1) atoms. There is one shorter (2.39 Å) and one longer (3.04 Å) Ga(1)-Ga(2) bond length. There is one shorter (2.61 Å) and one longer (3.04 Å) Ga(1)-Pb(1) bond length. In the second Ga site, Ga(2) is bonded in a 5-coordinate geometry to two equivalent Ga(1), two equivalent Al(1), and one Pb(1) atom. There is one shorter (2.61 Å) and one longer (3.04 Å) Ga(2)-Al(1) bond length. The Ga(2)-Pb(1) bond length is 3.28 Å. Al(1) is bonded in a single-bond geometry to two equivalent Ga(2) and one Pb(1) atom. The Al(1)-Pb(1) bond length is 0.60 Å. Pb(1) is bonded in a single-bond geometry to one Ga(2), two equivalent Ga(1), and one Al(1) atom.
