TiRhGe2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TiRhGe2 cluster. Ti(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Ge(1) atom. The Ti(1)-Rh(1) bond length is 1.50 Å. The Ti(1)-Ge(1) bond length is 1.50 Å. Rh(1) is bonded in a 3-coordinate geometry to one Ti(1), one Ge(1), and one Ge(2) atom. The Rh(1)-Ge(1) bond length is 0.66 Å. The Rh(1)-Ge(2) bond length is 0.67 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to one Ti(1), one Rh(1), and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 0.67 Å. In the second Ge site, Ge(2) is bonded in a 2-coordinate geometry to one Rh(1) and one Ge(1) atom.
