BeVNi2 crystallizes in the monoclinic Cm space group. Be(1) is bonded in a single-bond geometry to one V(1) and one Ni(1) atom. The Be(1)-V(1) bond length is 2.39 Å. The Be(1)-Ni(1) bond length is 0.22 Å. V(1) is bonded in a 8-coordinate geometry to one Be(1), six equivalent V(1), and one Ni(2) atom. All V(1)-V(1) bond lengths are 2.52 Å. The V(1)-Ni(2) bond length is 2.61 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a single-bond geometry to one Be(1) and one Ni(2) atom. The Ni(1)-Ni(2) bond length is 2.72 Å. In the second Ni site, Ni(2) is bonded in a 8-coordinate geometry to one V(1), one Ni(1), and six equivalent Ni(2) atoms. All Ni(2)-Ni(2) bond lengths are 2.52 Å.
