The material described by SmIrGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 14-coordinate geometry to four equivalent Ir(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Sm site, Sm(2) is bonded in a 15-coordinate geometry to six equivalent Ir(1), one Ge(1), two equivalent Ge(2), and six equivalent Ge(3) atoms. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Sm(1), three equivalent Sm(2), one Ge(1), one Ge(2), and three equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Sm(2), four equivalent Sm(1), and two equivalent Ir(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Sm(2), four equivalent Sm(1), two equivalent Ir(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Sm(1), three equivalent Sm(2), three equivalent Ir(1), and one Ge(3) atom. is represented by the CIF card [CIF]
