Sc3(MoGe2)2 is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 6-coordinate geometry to two equivalent Mo(1), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Sc site, Sc(2) is bonded in a 6-coordinate geometry to two equivalent Mo(1), one Ge(2), two equivalent Ge(1), and three equivalent Ge(3) atoms. Mo(1) is bonded in a 10-coordinate geometry to one Sc(1), two equivalent Sc(2), one Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Sc(1), four equivalent Sc(2), two equivalent Mo(1), and one Ge(2) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Sc(1), two equivalent Sc(2), four equivalent Mo(1), and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Sc(1), three equivalent Sc(2), and four equivalent Mo(1) atoms.
