Eu2MnRhO6 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. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 31-32°. Rh(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form RhO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 31-32°. 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 Mn(1), and one Rh(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Mn(1), and one Rh(1) atom. In the third O site, O(3) is bonded to two equivalent Eu(1), one Mn(1), and one Rh(1) atom to form distorted corner-sharing OEu2MnRh tetrahedra.
