The material structure described by KNaCl2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. K(1) is bonded to six equivalent Cl(1) atoms to form KCl6 octahedra that share corners with six equivalent Na(1)Cl6 octahedra, edges with six equivalent K(1)Cl6 octahedra, and edges with six equivalent Na(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 6°. Na(1) is bonded to six equivalent Cl(1) atoms to form NaCl6 octahedra that share corners with six equivalent K(1)Cl6 octahedra, edges with six equivalent K(1)Cl6 octahedra, and edges with six equivalent Na(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 6°. Cl(1) is bonded to three equivalent K(1) and three equivalent Na(1) atoms to form a mixture of corner and edge-sharing ClK3Na3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
