The compound described by Nd2IrGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to three equivalent Ir(1), three equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Nd site, Nd(2) is bonded in a 3-coordinate geometry to one Ir(1) and five equivalent Ge(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to one Nd(2), three equivalent Nd(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to three equivalent Nd(1), five equivalent Nd(2), and two equivalent Ir(1) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to three equivalent Nd(1), two equivalent Ir(1), and one Ge(2) atom. is represented by the CIF file [CIF]
