ScOsGe2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 12-coordinate geometry to four Os and eight Ge atoms. There are a spread of Sc–Os bond distances ranging from 3.08–3.17 Å. There are a spread of Sc–Ge bond distances ranging from 2.71–3.02 Å. In the second Sc site, Sc is bonded in a 7-coordinate geometry to six Os and seven Ge atoms. There are a spread of Sc–Os bond distances ranging from 3.14–3.27 Å. There are a spread of Sc–Ge bond distances ranging from 2.84–2.98 Å. There are two inequivalent Os sites. In the first Os site, Os is bonded in a 12-coordinate geometry to five Sc, one Os, and six Ge atoms. The Os–Os bond length is 2.86 Å. There are a spread of Os–Ge bond distances ranging from 2.45–2.72 Å. In the second Os site, Os is bonded in a 12-coordinate geometry to four Sc, two equivalent Os, and six Ge atoms. There are a spread of Os–Ge bond distances ranging from 2.54–2.63 Å. There are five inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to five Sc and four Os atoms. In the second Ge site, Ge is bonded in a 7-coordinate geometry to three Sc, three Os, and one Ge atom. The Ge–Ge bond length is 2.52 Å.
