Eu2RuCoO6 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(3), three equivalent O(1), and three equivalent O(2) 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 Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-33°. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-33°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Ru(1), and one Co(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Ru(1), and one Co(1) atom. In the third O site, O(3) is bonded to two equivalent Eu(1), one Ru(1), and one Co(1) atom to form distorted corner-sharing OEu2CoRu tetrahedra.
