Sc3(VGe2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Sc–Ge bond distances ranging from 2.61–3.00 Å. In the second Sc site, Sc is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Sc–Ge bond distances ranging from 2.63–2.82 Å. V is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of V–Ge bond distances ranging from 2.69–3.16 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Sc, two equivalent V, and one Ge atom. The Ge–Ge bond length is 2.56 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four Sc, four equivalent V, and one Ge atom. In the third Ge site, Ge is bonded in a 9-coordinate geometry to four Sc, four equivalent V, and one Ge atom. The Ge–Ge bond length is 2.75 Å.
