The crystal structure described by SrMg(RuO3)2 is Ilmenite-derived structured and crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share edges with six equivalent Ru(1)O6 octahedra. Ru(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RuO6 octahedra that share edges with three equivalent Mg(1)O6 octahedra and edges with three equivalent Ru(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Sr(1), one Mg(1), and two equivalent Ru(1) atoms to form a mixture of distorted edge and corner-sharing OSrMgRu2 trigonal pyramids. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Sr(1), one Mg(1), and two equivalent Ru(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
