LaBi2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two LaBi2 clusters. La(1) is bonded in a distorted single-bond geometry to one Bi(1) and one Bi(2) atom. The La(1)-Bi(1) bond length is 1.40 Å. The La(1)-Bi(2) bond length is 2.74 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted single-bond geometry to one La(1) atom. In the second Bi site, Bi(2) is bonded in a distorted single-bond geometry to one La(1) atom.
