KTlCl2 crystallizes in the cubic Fd-3m space group. K(1) is bonded to six equivalent Cl(1) atoms to form KCl6 octahedra that share corners with six equivalent Tl(1)Cl6 octahedra, edges with six equivalent K(1)Cl6 octahedra, and edges with six equivalent Tl(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 2°. Tl(1) is bonded to six equivalent Cl(1) atoms to form distorted TlCl6 octahedra that share corners with six equivalent K(1)Cl6 octahedra, edges with six equivalent K(1)Cl6 octahedra, and edges with six equivalent Tl(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 2°. Cl(1) is bonded to three equivalent K(1) and three equivalent Tl(1) atoms to form a mixture of distorted corner and edge-sharing ClK3Tl3 octahedra. The corner-sharing octahedra are not tilted.
