GaZn(Sn)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one distannene molecule and one GaZn cluster. In the GaZn cluster, Zn(1) is bonded in a single-bond geometry to one Ga(1) atom. The Zn(1)-Ga(1) bond length is 0.68 Å. Ga(1) is bonded in a single-bond geometry to one Zn(1) atom.
