The compound described by Yb2IrGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 8-coordinate geometry to two equivalent Ir(1), one Ge(2), and five equivalent Ge(1) atoms. In the second Yb site, Yb(2) is bonded in a 10-coordinate geometry to four equivalent Ir(1), two equivalent Ge(1), and five equivalent Ge(2) atoms. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Yb(1), four equivalent Yb(2), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Yb(2), five equivalent Yb(1), one Ir(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Yb(1), five equivalent Yb(2), three equivalent Ir(1), and one Ge(2) atom. is represented by the CIF file [CIF]
