ScMn6GaGe5 crystallizes in the hexagonal P-6m2 space group. Sc(1) is bonded to two equivalent Ge(3), three equivalent Ge(1), and three equivalent Ge(2) atoms to form distorted edge-sharing ScGe8 hexagonal bipyramids. Mn(1) is bonded in a 6-coordinate geometry to one Ga(1), one Ge(1), one Ge(2), one Ge(4), and two equivalent Ge(3) atoms. Ga(1) is bonded in a 9-coordinate geometry to six equivalent Mn(1) and three equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Mn(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Sc(1), six equivalent Mn(1), and one Ge(3) atom. In the fourth Ge site, Ge(4) is bonded in a 6-coordinate geometry to six equivalent Mn(1) and three equivalent Ga(1) atoms.
