Rh2InGe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Rh2InGe cluster. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one In(1) and one Ge(1) atom. The Rh(1)-In(1) bond length is 2.23 Å. The Rh(1)-Ge(1) bond length is 1.95 Å. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one In(1) atom. The Rh(2)-In(1) bond length is 2.23 Å. In(1) is bonded in a 3-coordinate geometry to one Rh(1), one Rh(2), and one Ge(1) atom. The In(1)-Ge(1) bond length is 1.42 Å. Ge(1) is bonded in a 2-coordinate geometry to one Rh(1) and one In(1) atom.
