K3Na(RuO4)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to one O(4), two equivalent O(2), three equivalent O(1), and three equivalent O(3) atoms. In the second K site, K(2) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and four equivalent O(4) atoms. Na(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NaO6 octahedra that share corners with six equivalent Ru(1)O4 tetrahedra. Ru(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form RuO4 tetrahedra that share corners with three equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-41°. There are four inequivalent O sites. In the first O site, O(3) is bonded in a 6-coordinate geometry to one K(2), three equivalent K(1), one Na(1), and one Ru(1) atom. In the second O site, O(4) is bonded in a 3-coordinate geometry to one K(1), two equivalent K(2), and one Ru(1) atom.
