The material structure described by Sm2AlGe6 crystallizes in the monoclinic C2/m space group. Sm(1) is bonded in a 12-coordinate geometry to two equivalent Al(1), one Ge(4), one Ge(5), two equivalent Ge(1), three equivalent Ge(2), and three equivalent Ge(3) atoms. Al(1) is bonded in a 5-coordinate geometry to four equivalent Sm(1), one Ge(3), one Ge(4), one Ge(5), and two equivalent Ge(1) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to two equivalent Sm(1), one Al(1), one Ge(1), one Ge(4), and one Ge(5) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to six equivalent Sm(1), one Ge(2), and one Ge(3) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Al(1), one Ge(2), and one Ge(3) atom. In the fourth Ge site, Ge(4) is bonded in a 6-coordinate geometry to two equivalent Sm(1), one Al(1), one Ge(4), and two equivalent Ge(1) atoms. In the fifth Ge site, Ge(5) is bonded in a 6-coordinate geometry to two equivalent Sm(1), one Al(1), one Ge(5), and two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
