AlGeBi2 crystallizes in the triclinic P1 space group. Al(1) is bonded in a distorted bent 120 degrees geometry to one Ge(1), one Bi(1), and one Bi(2) atom. The Al(1)-Ge(1) bond length is 2.44 Å. The Al(1)-Bi(1) bond length is 3.04 Å. The Al(1)-Bi(2) bond length is 2.58 Å. Ge(1) is bonded in a distorted single-bond geometry to one Al(1) and two equivalent Bi(1) atoms. There is one shorter (2.91 Å) and one longer (3.24 Å) Ge(1)-Bi(1) bond length. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to one Al(1), two equivalent Ge(1), two equivalent Bi(1), and three equivalent Bi(2) atoms. Both Bi(1)-Bi(1) bond lengths are 3.41 Å. There are a spread of Bi(1)-Bi(2) bond distances ranging from 2.33-3.41 Å. In the second Bi site, Bi(2) is bonded in a 2-coordinate geometry to one Al(1) and three equivalent Bi(1) atoms.
