The crystal structure described by KTlO2 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 Tl(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Tl(1)O6 octahedra. The corner-sharing octahedral tilt angles are 12°. Tl(1) is bonded to six equivalent O(1) atoms to form TlO6 octahedra that share corners with six equivalent K(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Tl(1)O6 octahedra. The corner-sharing octahedral tilt angles are 12°. O(1) is bonded to three equivalent K(1) and three equivalent Tl(1) atoms to form a mixture of edge and corner-sharing OK3Tl3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
