Materials Data on KCoCl3 by Materials Project
KCoCl3 is Orthorhombic Perovskite-like structured and crystallizes in the trigonal R3c space group. The structure is three-dimensional. K1+ is bonded in a 12-coordinate geometry to twelve equivalent Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.16–3.79 Å. Co2+ is bonded to six equivalent Cl1- atoms to form corner-sharing CoCl6 octahedra. The corner-sharing octahedral tilt angles are 15°. There are three shorter (2.46 Å) and three longer (2.47 Å) Co–Cl bond lengths. Cl1- is bonded in a 5-coordinate geometry to four equivalent K1+ and two equivalent Co2+ atoms.
