Be Al Al Au
BeAuAl2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeAuAl2 cluster. Be(1) is bonded in a bent 150 degrees geometry to one Au(1) and one Al(1) atom. The Be(1)-Au(1) bond length is 1.88 Å. The Be(1)-Al(1) bond length is 0.15 Å. Au(1) is bonded in a distorted linear geometry to one Be(1) and one Al(2) atom. The Au(1)-Al(2) bond length is 1.00 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one Be(1) atom. In the second Al site, Al(2) is bonded in a single-bond geometry to one Au(1) atom.
