The material structure described by K3Na(RuO4)2 crystallizes in the trigonal P-3m1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to one O(2) and nine equivalent O(1) atoms. In the second K site, K(2) is bonded in a distorted hexagonal planar geometry to six equivalent O(1) atoms. Na(1) is bonded to six equivalent O(1) atoms to form NaO6 octahedra that share corners with six equivalent Ru(1)O4 tetrahedra. Ru(1) is bonded to one O(2) and three equivalent O(1) atoms to form RuO4 tetrahedra that share corners with three equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are two inequivalent O sites. In the first O site, O(1) 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(2) is bonded in a linear geometry to one K(1) and one Ru(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
