The compound described by DyIrGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) 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. In the second Dy site, Dy(2) is bonded in a 15-coordinate geometry to six equivalent Ir(1), one Ge(1), two equivalent Ge(2), and six equivalent Ge(3) atoms. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Dy(1), three equivalent Dy(2), 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 2-coordinate geometry to one Dy(2), four equivalent Dy(1), and two equivalent Ir(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), two equivalent Ir(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Dy(1), three equivalent Dy(2), three equivalent Ir(1), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
