RhGe3 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a distorted single-bond geometry to one Ge(2) and one Ge(3) atom. The Rh(1)-Ge(2) bond length is 1.87 Å. The Rh(1)-Ge(3) bond length is 2.98 Å. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Ge(2) and one Ge(3) atom. The Ge(1)-Ge(2) bond length is 1.11 Å. The Ge(1)-Ge(3) bond length is 2.74 Å. In the second Ge site, Ge(2) is bonded in a linear geometry to one Rh(1) and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Rh(1), one Ge(1), and six equivalent Ge(3) atoms. All Ge(3)-Ge(3) bond lengths are 3.06 Å.
