The structure described by KEuO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. K(1) is bonded to six equivalent O(1) atoms to form distorted KO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 13°. Eu(1) is bonded to six equivalent O(1) atoms to form EuO6 octahedra that share corners with six equivalent K(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 13°. O(1) is bonded to three equivalent K(1) and three equivalent Eu(1) atoms to form a mixture of corner and edge-sharing OK3Eu3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
