Be Al Cd
BeCdAl is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeCdAl cluster. Be(1) is bonded in a single-bond geometry to one Al(1) atom. The Be(1)-Al(1) bond length is 0.68 Å. Cd(1) is bonded in a single-bond geometry to one Al(1) atom. The Cd(1)-Al(1) bond length is 0.45 Å. Al(1) is bonded in a linear geometry to one Be(1) and one Cd(1) atom.
