VNi2Zn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VNi2Zn cluster. V(1) is bonded in a distorted single-bond geometry to one Ni(2) atom. The V(1)-Ni(2) bond length is 1.53 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 2-coordinate geometry to one Ni(2) and one Zn(1) atom. The Ni(1)-Ni(2) bond length is 0.18 Å. The Ni(1)-Zn(1) bond length is 1.55 Å. In the second Ni site, Ni(2) is bonded in a distorted bent 150 degrees geometry to one V(1) and one Ni(1) atom. Zn(1) is bonded in a distorted single-bond geometry to one Ni(1) atom.
