The structure described by Rb3NaMg(RuO4)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to one O(3), two equivalent O(2), and three equivalent O(1) atoms. In the second Rb site, Rb(2) is bonded in a distorted linear geometry to two equivalent O(1) atoms. Na(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Ru(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Rb(2), three equivalent Rb(1), and one Ru(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Rb(1), one Na(1), one Mg(1), and one Ru(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Rb(1) and one Ru(1) atom. is represented by the CIF file [CIF]
