The material described by ScMn6(Sn2Ge)2 crystallizes in the hexagonal P6/mmm space group. Sc(1) is bonded to two equivalent Sn(2) and six equivalent Ge(1) atoms to form distorted edge-sharing ScSn2Ge6 hexagonal bipyramids. Mn(1) is bonded in a 6-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Ge(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to six equivalent Mn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to one Sc(1), six equivalent Mn(1), and one Sn(2) atom. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Mn(1) atoms. is represented by the CIF card [CIF]
