Be2NiCd is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Be2NiCd cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 2-coordinate geometry to one Be(2) and one Ni(1) atom. The Be(1)-Be(2) bond length is 0.92 Å. The Be(1)-Ni(1) bond length is 1.90 Å. In the second Be site, Be(2) is bonded in a distorted single-bond geometry to one Be(1) atom. Ni(1) is bonded in a 2-coordinate geometry to one Be(1) and one Cd(1) atom. The Ni(1)-Cd(1) bond length is 2.22 Å. Cd(1) is bonded in a distorted single-bond geometry to one Ni(1) atom.
