The structure described by Eu2RuNiO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Ru(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form RuO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-31°. Ni(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NiO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-31°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Eu(1), one Ru(1), and one Ni(1) atom to form distorted corner-sharing OEu2NiRu tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Ru(1), and one Ni(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Ru(1), and one Ni(1) atom. is represented by the CIF file [CIF]
