BaCdGe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaCdGe clusters. Ba(1) is bonded in a 1-coordinate geometry to one Cd(1) atom. The Ba(1)-Cd(1) bond length is 2.11 Å. Cd(1) is bonded in a linear geometry to one Ba(1) and one Ge(1) atom. The Cd(1)-Ge(1) bond length is 1.35 Å. Ge(1) is bonded in a distorted single-bond geometry to one Cd(1) atom.
