Rh2CoGe crystallizes in the monoclinic Cm space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to one Rh(2) and four equivalent Co(1) atoms. The Rh(1)-Rh(2) bond length is 1.90 Å. There are a spread of Rh(1)-Co(1) bond distances ranging from 1.71-2.32 Å. In the second Rh site, Rh(2) is bonded in a 1-coordinate geometry to one Rh(1) and one Ge(1) atom. The Rh(2)-Ge(1) bond length is 2.97 Å. Co(1) is bonded in a 3-coordinate geometry to four equivalent Rh(1) and one Ge(1) atom. The Co(1)-Ge(1) bond length is 2.50 Å. Ge(1) is bonded in a 2-coordinate geometry to one Rh(2) and one Co(1) atom.
