Be Cd Ni Ni
BeNi2Cd is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeNi2Cd cluster. Be(1) is bonded in an L-shaped geometry to one Ni(2) and one Cd(1) atom. The Be(1)-Ni(2) bond length is 0.62 Å. The Be(1)-Cd(1) bond length is 0.62 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 Cd(1) atom. The Ni(1)-Ni(2) bond length is 1.35 Å. The Ni(1)-Cd(1) bond length is 1.35 Å. In the second Ni site, Ni(2) is bonded in a distorted single-bond geometry to one Be(1), one Ni(1), and one Cd(1) atom. The Ni(2)-Cd(1) bond length is 0.81 Å. Cd(1) is bonded in a 3-coordinate geometry to one Be(1), one Ni(1), and one Ni(2) atom.
