The structure described by Eu2MgIrO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with six equivalent Ir(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-29°. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(2), three equivalent O(1), and three equivalent O(3) atoms. Ir(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form IrO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-29°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Mg(1), three equivalent Eu(1), and one Ir(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mg(1), two equivalent Eu(1), and one Ir(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Mg(1), three equivalent Eu(1), and one Ir(1) atom. is represented by the CIF card [CIF]
