The crystal structure described by KMgRuO3 crystallizes in the tetragonal P4/mmm space group. K(1) is bonded to two equivalent Mg(1) and four equivalent O(2) atoms to form distorted KMg2O4 octahedra that share corners with six equivalent K(1)Mg2O4 octahedra, corners with eight equivalent Ru(1)O6 octahedra, and edges with four equivalent K(1)Mg2O4 octahedra. The corner-sharing octahedral tilt angles range from 0-90°. Mg(1) is bonded in a distorted square co-planar geometry to two equivalent K(1) and four equivalent O(1) atoms. Ru(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RuO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra and corners with eight equivalent K(1)Mg2O4 octahedra. The corner-sharing octahedral tilt angles range from 0-90°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Ru(1) atoms. In the second O site, O(2) is bonded to four equivalent K(1) and two equivalent Ru(1) atoms to form a mixture of edge and corner-sharing OK4Ru2 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
