Materials Data on KCl by Materials Project
KCl is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. K1+ is bonded to six equivalent Cl1- atoms to form a mixture of corner and edge-sharing KCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All K–Cl bond lengths are 3.19 Å. Cl1- is bonded to six equivalent K1+ atoms to form a mixture of corner and edge-sharing ClK6 octahedra. The corner-sharing octahedral tilt angles are 0°.
