The material structure described by EuIrGe2 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 14-coordinate geometry to four equivalent Ir(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. Ir(1) is bonded in a 5-coordinate geometry to four equivalent Eu(1), one Ge(1), and four 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 six equivalent Eu(1), one Ir(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Ir(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
