BeAg2Al crystallizes in the triclinic P1 space group. Be(1) is bonded in a distorted bent 120 degrees geometry to one Ag(1), one Ag(2), and one Al(1) atom. The Be(1)-Ag(1) bond length is 2.35 Å. The Be(1)-Ag(2) bond length is 1.38 Å. The Be(1)-Al(1) bond length is 1.69 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 8-coordinate geometry to one Be(1), two equivalent Ag(1), two equivalent Ag(2), and three equivalent Al(1) atoms. Both Ag(1)-Ag(1) bond lengths are 2.94 Å. There is one shorter (1.85 Å) and one longer (2.93 Å) Ag(1)-Ag(2) bond length. There are a spread of Ag(1)-Al(1) bond distances ranging from 2.42-3.15 Å. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Be(1), two equivalent Ag(1), and one Al(1) atom. The Ag(2)-Al(1) bond length is 2.42 Å. Al(1) is bonded in a 4-coordinate geometry to one Be(1), one Ag(2), and three equivalent Ag(1) atoms.
