The structure described by Sm3Ge5 crystallizes in the hexagonal P-62c space group. Sm(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), and six equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Ge(1) atoms. In the second Ge site, Ge(3) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Ge(1) atoms. In the third Ge site, Ge(1) is bonded in a 8-coordinate geometry to six equivalent Sm(1), one Ge(2), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
