(Ga)4CGa(C)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one acetylene molecule, two digallane molecules, and one CGa cluster. In the CGa cluster, Ga(1) is bonded in a distorted single-bond geometry to one C(1) atom. The Ga(1)-C(1) bond length is 1.57 Å. C(1) is bonded in a 1-coordinate geometry to one Ga(1) atom.
