Materials Data on K2BrCl by Materials Project
KCl(KBr) is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. K1+ is bonded to three equivalent Br1- and three equivalent Cl1- atoms to form a mixture of corner and edge-sharing KBr3Cl3 octahedra. The corner-sharing octahedral tilt angles are 0°. All K–Br bond lengths are 3.32 Å. All K–Cl bond lengths are 3.22 Å. Br1- is bonded to six equivalent K1+ atoms to form BrK6 octahedra that share corners with six equivalent ClK6 octahedra, edges with six equivalent BrK6 octahedra, and edges with six equivalent ClK6 octahedra. The corner-sharing octahedral tilt angles are 2°. Cl1- is bonded to six equivalent K1+ atoms to form ClK6 octahedra that share corners with six equivalent BrK6 octahedra, edges with six equivalent BrK6 octahedra, and edges with six equivalent ClK6 octahedra. The corner-sharing octahedral tilt angles are 2°.
