The material structure described by Sm11Ge4In6 crystallizes in the tetragonal I4/mmm space group. There are four inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 9-coordinate geometry to four equivalent In(1), four equivalent In(2), and one Ge(2) atom. In the second Sm site, Sm(2) is bonded to four equivalent In(1), one Ge(1), one Ge(2), and one Ge(3) atom to form a mixture of distorted edge, face, and corner-sharing SmIn4Ge3 pentagonal bipyramids. In the third Sm site, Sm(3) is bonded in a 7-coordinate geometry to two equivalent In(1), two equivalent In(2), one Ge(3), and two equivalent Ge(1) atoms. In the fourth Sm site, Sm(4) is bonded in a 7-coordinate geometry to one In(2), two equivalent In(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to one Sm(1), one Sm(4), two equivalent Sm(3), four equivalent Sm(2), one In(1), and one In(2) atom. In the second In site, In(2) is bonded in a 11-coordinate geometry to one Sm(4), two equivalent Sm(1), four equivalent Sm(3), two equivalent In(1), and two equivalent In(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to two equivalent Sm(2), two equivalent Sm(4), and four equivalent Sm(3) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Sm(1), four equivalent Sm(2), and four equivalent Sm(4) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to four equivalent Sm(2) and four equivalent Sm(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
