Sm2RuGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 6-coordinate geometry to two equivalent Ru and six Ge atoms. Both Sm–Ru bond lengths are 3.37 Å. There are a spread of Sm–Ge bond distances ranging from 2.96–3.34 Å. In the second Sm site, Sm is bonded in a 2-coordinate geometry to four equivalent Ru and seven Ge atoms. There are a spread of Sm–Ru bond distances ranging from 3.13–3.29 Å. There are a spread of Sm–Ge bond distances ranging from 3.00–3.49 Å. Ru is bonded in a 4-coordinate geometry to six Sm and four Ge atoms. There are a spread of Ru–Ge bond distances ranging from 2.48–2.62 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Sm, one Ru, and one Ge atom. The Ge–Ge bond length is 2.72 Å. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Sm, three equivalent Ru, and one Ge atom. The Ge–Ge bond length is 2.91 Å.
