The compound described by SrMg(RuO3)2 is Ilmenite-derived structured and crystallizes in the monoclinic C2 space group. Sr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SrO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra, corners with six equivalent Ru(2)O6 octahedra, and edges with three equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-58°. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted MgO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra, edges with three equivalent Sr(1)O6 octahedra, and faces with two equivalent Ru(2)O6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are two inequivalent Ru sites. In the first Ru site, 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 Sr(1)O6 octahedra, corners with six equivalent Mg(1)O6 octahedra, and edges with three equivalent Ru(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-58°. In the second Ru site, Ru(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted RuO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra, edges with three equivalent Ru(1)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), one Ru(1), and one Ru(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), one Ru(1), and one Ru(2) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), one Ru(1), and one Ru(2) atom. is represented by the CIF card [CIF]
