Al Ag Ag Bi
Ag2AlBi crystallizes in the triclinic P1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Ag(2) and two equivalent Al(1) atoms. The Ag(1)-Ag(2) bond length is 2.65 Å. There is one shorter (2.00 Å) and one longer (2.48 Å) Ag(1)-Al(1) bond length. In the second Ag site, Ag(2) is bonded in a 7-coordinate geometry to one Ag(1), four equivalent Ag(2), and two equivalent Bi(1) atoms. There are two shorter (3.21 Å) and two longer (3.42 Å) Ag(2)-Ag(2) bond lengths. There is one shorter (2.98 Å) and one longer (3.32 Å) Ag(2)-Bi(1) bond length. Al(1) is bonded in a 1-coordinate geometry to two equivalent Ag(1) and one Bi(1) atom. The Al(1)-Bi(1) bond length is 1.32 Å. Bi(1) is bonded in a single-bond geometry to two equivalent Ag(2) and one Al(1) atom.
