HfRhGe2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Hf sites. In the first Hf site, Hf is bonded in a 12-coordinate geometry to four Rh and eight Ge atoms. There are a spread of Hf–Rh bond distances ranging from 3.08–3.27 Å. There are a spread of Hf–Ge bond distances ranging from 2.75–3.04 Å. In the second Hf site, Hf is bonded in a 7-coordinate geometry to six Rh and seven Ge atoms. There are a spread of Hf–Rh bond distances ranging from 3.05–3.28 Å. There are a spread of Hf–Ge bond distances ranging from 2.82–2.99 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 12-coordinate geometry to five Hf, one Rh, and six Ge atoms. The Rh–Rh bond length is 2.85 Å.
