Ga Ni Ni Sn
NiGaNiSn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one lambda~2~-stannane--nickel (1/1) molecule and one NiGa cluster. In the NiGa cluster, Ni(2) is bonded in a single-bond geometry to one Ga(1) atom. The Ni(2)-Ga(1) bond length is 0.90 Å. Ga(1) is bonded in a single-bond geometry to one Ni(2) atom.
