The material structure described by Er2RuNiO6 crystallizes in the monoclinic P2_1/c space group. Er(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 38-42°. 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 38-42°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Er(1), one Ru(1), and one Ni(1) atom to form distorted corner-sharing OEr2NiRu trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Er(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 Er(1), one Ru(1), and one Ni(1) atom. is represented by the CIF card [CIF]
