KDyO2 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 Dy(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Dy(1)O6 octahedra. The corner-sharing octahedral tilt angles are 14°. Dy(1) is bonded to six equivalent O(1) atoms to form DyO6 octahedra that share corners with six equivalent K(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Dy(1)O6 octahedra. The corner-sharing octahedral tilt angles are 14°. O(1) is bonded to three equivalent K(1) and three equivalent Dy(1) atoms to form a mixture of distorted edge and corner-sharing OK3Dy3 octahedra. The corner-sharing octahedra are not tilted.
