The material structure described by Sm2Ir3Ge5 crystallizes in the orthorhombic Ibam space group. Sm(1) is bonded in a 17-coordinate geometry to two equivalent Ir(2), five equivalent Ir(1), two equivalent Ge(1), four equivalent Ge(2), and four equivalent Ge(3) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to five equivalent Sm(1), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. In the second Ir site, Ir(2) is bonded in a 6-coordinate geometry to four equivalent Sm(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent Ir(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Ir(2), two equivalent Ir(1), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Ir(1), two equivalent Ir(2), and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
