CeGa crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one CeGa cluster. Ce(1) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one Ga(1) atom. The Ce(1)-Ce(1) bond length is 0.47 Å. The Ce(1)-Ga(1) bond length is 0.96 Å. Ga(1) is bonded in a single-bond geometry to one Ce(1) atom.
