Materials Data on KI by Materials Project

IK1 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 I1- atoms to form a mixture of edge and corner-sharing KI6 octahedra. The corner-sharing octahedral tilt angles are 0°. All K–I bond lengths are 3.59 Å. I1- is bonded to six equivalent K1+ atoms to form a mixture of edge and corner-sharing IK6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on KI by Materials Project

IK1 is Molybdenum Carbide MAX Phase-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded to six equivalent I1- atoms to form a mixture of corner, edge, and face-sharing KI6 octahedra. The corner-sharing octahedra tilt angles range from 45–48°. There are a spread of K–I bond distances ranging from 3.58–3.63 Å. I1- is bonded to six equivalent K1+ atoms to form a mixture of distorted corner and edge-sharing IK6 pentagonal pyramids.
