Ce3Rh4Ge4 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 12-coordinate geometry to eight Rh and six Ge atoms. There are a spread of Ce–Rh bond distances ranging from 3.17–3.44 Å. There are two shorter (3.15 Å) and four longer (3.20 Å) Ce–Ge bond lengths. In the second Ce site, Ce is bonded to four equivalent Rh and eight equivalent Ge atoms to form a mixture of face and edge-sharing CeGe8Rh4 cuboctahedra. All Ce–Rh bond lengths are 3.18 Å. All Ce–Ge bond lengths are 3.19 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 3-coordinate geometry to six Ce and three Ge atoms. There are two shorter (2.47 Å) and one longer (2.48 Å) Rh–Ge bond lengths. In the second Rh site, Rh is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Ge atoms. There are two shorter (2.45 Å) and two longer (2.52 Å) Rh–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ce and five Rh atoms. In the second Ge site, Ge is bonded in a 2-coordinate geometry to six Ce, two equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.48 Å.
