NiGaGe2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NiGaGe2 cluster. Ni(1) is bonded in a 2-coordinate geometry to one Ga(1) and one Ge(2) atom. The Ni(1)-Ga(1) bond length is 0.18 Å. The Ni(1)-Ge(2) bond length is 0.18 Å. Ga(1) is bonded in a single-bond geometry to one Ni(1), one Ge(1), and one Ge(2) atom. The Ga(1)-Ge(1) bond length is 0.11 Å. The Ga(1)-Ge(2) bond length is 0.06 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Ga(1) and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 0.11 Å. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one Ni(1), one Ga(1), and one Ge(1) atom.
