Al V V Ni
V2NiAl is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two V2NiAl clusters. V(1) is bonded in a distorted L-shaped geometry to one Ni(1) and one Al(1) atom. The V(1)-Ni(1) bond length is 0.74 Å. The V(1)-Al(1) bond length is 0.74 Å. Ni(1) is bonded in an L-shaped geometry to two equivalent V(1) atoms. Al(1) is bonded in an L-shaped geometry to two equivalent V(1) atoms.
