SmRh5Ge3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 12-coordinate geometry to six Rh and six Ge atoms. There are a spread of Sm–Rh bond distances ranging from 3.16–3.23 Å. There are a spread of Sm–Ge bond distances ranging from 3.13–3.16 Å. In the second Sm site, Sm is bonded in a 12-coordinate geometry to six Rh and six Ge atoms. There are a spread of Sm–Rh bond distances ranging from 3.10–3.29 Å. There are four shorter (3.10 Å) and two longer (3.23 Å) Sm–Ge bond lengths. There are ten inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.46–2.60 Å. In the second Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Sm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.45–2.54 Å. In the third Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Sm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.47–2.55 Å. In the fourth Rh site, Rh is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.45–2.60 Å. In the fifth Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Sm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.45–2.52 Å. In the sixth Rh site, Rh is bonded in a 2-coordinate geometry to two equivalent Sm, six Rh, and two Ge atoms. There are two shorter (2.74 Å) and four longer (2.85 Å) Rh–Rh bond lengths. Both Rh–Ge bond lengths are 2.47 Å. In the seventh Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Sm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.46–2.54 Å. In the eighth Rh site, Rh is bonded in a 12-coordinate geometry to four equivalent Rh and four Ge atoms. There are two shorter (2.61 Å) and two longer (2.62 Å) Rh–Ge bond lengths. In the ninth Rh site, Rh is bonded in a 3-coordinate geometry to three equivalent Ge atoms. There are one shorter (2.43 Å) and two longer (2.61 Å) Rh–Ge bond lengths. In the tenth Rh site, Rh is bonded in a 4-coordinate geometry to two equivalent Sm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.48–2.55 Å. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Sm and seven Rh atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Sm and seven Rh atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Sm and seven Rh atoms. In the fourth Ge site, Ge is bonded in a 10-coordinate geometry to two equivalent Sm and six Rh atoms. In the fifth Ge site, Ge is bonded in a 10-coordinate geometry to two equivalent Sm and six Rh atoms. In the sixth Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Sm and six Rh atoms.
