V2NiGa is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two V2NiGa clusters. V(1) is bonded in an L-shaped geometry to one Ni(1) and one Ga(1) atom. The V(1)-Ni(1) bond length is 0.84 Å. The V(1)-Ga(1) bond length is 0.84 Å. Ni(1) is bonded in an L-shaped geometry to two equivalent V(1) atoms. Ga(1) is bonded in an L-shaped geometry to two equivalent V(1) atoms.
