CdGeAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CdGeAs clusters. Cd(1) is bonded in a linear geometry to one Ge(1) and one As(1) atom. The Cd(1)-Ge(1) bond length is 0.61 Å. The Cd(1)-As(1) bond length is 0.52 Å. Ge(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. As(1) is bonded in a distorted single-bond geometry to one Cd(1) atom.
