BeLaAl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeLaAl clusters. Be(1) is bonded in a single-bond geometry to one Al(1) atom. The Be(1)-Al(1) bond length is 0.20 Å. La(1) is bonded in a single-bond geometry to one Al(1) atom. The La(1)-Al(1) bond length is 2.17 Å. Al(1) is bonded in a distorted linear geometry to one Be(1) and one La(1) atom.
