Be Be V Ni
Be2VNi crystallizes in the monoclinic Cm space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted bent 150 degrees geometry to one Be(2) and one Ni(1) atom. The Be(1)-Be(2) bond length is 1.68 Å. The Be(1)-Ni(1) bond length is 2.68 Å. In the second Be site, Be(2) is bonded in a distorted bent 150 degrees geometry to one Be(1) and one V(1) atom. The Be(2)-V(1) bond length is 1.40 Å. V(1) is bonded in a 4-coordinate geometry to one Be(2) and three equivalent Ni(1) atoms. There is one shorter (1.17 Å) and two longer (2.09 Å) V(1)-Ni(1) bond lengths. Ni(1) is bonded in a distorted single-bond geometry to one Be(1) and three equivalent V(1) atoms.
