BeLaAs2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeLaAs2 clusters. Be(1) is bonded in an L-shaped geometry to two equivalent As(1) atoms. Both Be(1)-As(1) bond lengths are 1.09 Å. La(1) is bonded in an L-shaped geometry to two equivalent As(1) atoms. Both La(1)-As(1) bond lengths are 1.09 Å. As(1) is bonded in an L-shaped geometry to one Be(1) and one La(1) atom.
