NdIrGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 15-coordinate geometry to six equivalent Ir(1), one Ge(2), two equivalent Ge(1), and six equivalent Ge(3) atoms. In the second Nd site, Nd(2) 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. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Nd(2), three equivalent Nd(1), 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 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), two equivalent Ir(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 2-coordinate geometry to one Nd(1), four equivalent Nd(2), and two equivalent Ir(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Nd(2), three equivalent Nd(1), three equivalent Ir(1), and one Ge(3) atom.
