Be Cd Cd Ge
BeCd2Ge is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeCd2Ge clusters. Be(1) is bonded in a distorted linear geometry to one Cd(1) and one Ge(1) atom. The Be(1)-Cd(1) bond length is 2.12 Å. The Be(1)-Ge(1) bond length is 1.57 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a distorted linear geometry to one Be(1) and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 2.02 Å. In the second Cd site, Cd(2) is bonded in a distorted single-bond geometry to one Cd(1) atom. Ge(1) is bonded in a single-bond geometry to one Be(1) atom.
