The compound described by ScMnGe2 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 8-coordinate geometry to one Ge(4), one Ge(5), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Sc site, Sc(2) is bonded to two equivalent Ge(1), two equivalent Ge(2), and three equivalent Ge(4) atoms to form a mixture of distorted edge and corner-sharing ScGe7 pentagonal bipyramids. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 6-coordinate geometry to one Ge(2), one Ge(3), one Ge(4), one Ge(5), and two equivalent Ge(1) atoms. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to two equivalent Ge(1), two equivalent Ge(4), and two equivalent Ge(5) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Sc(2), four equivalent Sc(1), two equivalent Mn(1), and one Ge(2) atom. In the second Ge site, Ge(3) is bonded in a 7-coordinate geometry to four equivalent Sc(1), two equivalent Mn(1), and one Ge(3) atom. In the third Ge site, Ge(4) is bonded in a 9-coordinate geometry to two equivalent Sc(1), three equivalent Sc(2), two equivalent Mn(1), and two equivalent Mn(2) atoms. In the fourth Ge site, Ge(5) is bonded in a 6-coordinate geometry to two equivalent Sc(1), two equivalent Mn(1), and two equivalent Mn(2) atoms.
