CoLi2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CoLi2 cluster. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a single-bond geometry to one Co(1) atom. The Li(1)-Co(1) bond length is 1.32 Å. In the second Li site, Li(2) is bonded in a single-bond geometry to one Co(1) atom. The Li(2)-Co(1) bond length is 1.40 Å. Co(1) is bonded in a linear geometry to one Li(1) and one Li(2) atom.
