CdRh(Ge)4 is Zincblende, Sphalerite structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three CdRh clusters and three Ge clusters. In each CdRh cluster, Rh(1) is bonded in a single-bond geometry to one Cd(1) atom. The Rh(1)-Cd(1) bond length is 0.98 Å. Cd(1) is bonded in a distorted single-bond geometry to one Rh(1) atom. In each Ge cluster, there are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Ge(2) and two equivalent Ge(1) atoms. The Ge(1)-Ge(2) bond length is 0.53 Å. Both Ge(1)-Ge(1) bond lengths are 0.31 Å. In the second Ge site, Ge(2) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms.
