The material structure described by KRu4O8 crystallizes in the tetragonal I4/m space group. K(1) is bonded in a body-centered cubic geometry to eight equivalent O(2) atoms. Ru(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Ru(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent K(1) and three equivalent Ru(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
