The material structure described by La2Ir3Ge5 crystallizes in the orthorhombic Ibam space group. La(1) is bonded in a 17-coordinate geometry to two equivalent Ir(2), five equivalent Ir(1), two equivalent Ge(2), four equivalent Ge(1), and four equivalent Ge(3) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a 6-coordinate geometry to four equivalent La(1), two equivalent Ge(1), and four equivalent Ge(3) atoms. In the second Ir site, Ir(1) is bonded in a 8-coordinate geometry to five equivalent La(1), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ir(2), two equivalent Ir(1), and two equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Ir(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ir(1), two equivalent Ir(2), and two equivalent Ge(1) atoms. is represented by the CIF file [CIF]
