The material structure described by EuIrIn4 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 15-coordinate geometry to two equivalent Ir(1), three equivalent In(2), four equivalent In(3), and six equivalent In(1) atoms. Ir(1) is bonded in a 9-coordinate geometry to two equivalent Eu(1), one In(2), and six equivalent In(1) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to three equivalent Eu(1), three equivalent Ir(1), and one In(3) atom. In the second In site, In(2) is bonded in a 1-coordinate geometry to three equivalent Eu(1), one Ir(1), and four equivalent In(3) atoms. In the third In site, In(3) is bonded in a distorted q6 geometry to four equivalent Eu(1), two equivalent In(1), and four equivalent In(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
