BeLa2V crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeLa2V clusters. Be(1) is bonded in a distorted single-bond geometry to one La(1) atom. The Be(1)-La(1) bond length is 2.10 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a distorted water-like geometry to one Be(1) and one V(1) atom. The La(1)-V(1) bond length is 1.43 Å. In the second La site, La(2) is bonded in a single-bond geometry to one V(1) atom. The La(2)-V(1) bond length is 1.43 Å. V(1) is bonded in an L-shaped geometry to one La(1) and one La(2) atom.
