The structure described by SrMg(RuO3)2 crystallizes in the orthorhombic Imm2 space group. Sr(1) is bonded in a 5-coordinate geometry to one O(3) and four equivalent O(1) atoms. Mg(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Ru(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles range from 27-45°. 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), and two equivalent Ru(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent Ru(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent Ru(1) atoms. is represented by the CIF file [CIF]
