The crystal structure described by La(IrGe)2 crystallizes in the tetragonal P4/nmm space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Ir(1), four equivalent Ir(2), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Ge(2) atoms. In the second Ir site, Ir(2) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Ir(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ir(2), and four equivalent Ir(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
