Ba3Rh4Ge16 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded in a 4-coordinate geometry to two equivalent Rh and sixteen Ge atoms. Both Ba–Rh bond lengths are 3.61 Å. There are four shorter (3.53 Å) and twelve longer (3.58 Å) Ba–Ge bond lengths. In the second Ba site, Ba is bonded in a 8-coordinate geometry to eight equivalent Rh and sixteen Ge atoms. All Ba–Rh bond lengths are 3.87 Å. There are eight shorter (3.64 Å) and eight longer (3.68 Å) Ba–Ge bond lengths. Rh is bonded in a 6-coordinate geometry to three Ba and six Ge atoms. There are two shorter (2.49 Å) and four longer (2.51 Å) Rh–Ge bond lengths. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to three Ba, two equivalent Rh, and two Ge atoms. There are one shorter (2.74 Å) and one longer (2.76 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ba and two equivalent Rh atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ba and five Ge atoms. The Ge–Ge bond length is 2.55 Å. In the fourth Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ba and five Ge atoms.
