Materials Data on CsK2AsCl6 by Materials Project
(K)2CsAsCl6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight potassium molecules and one CsAsCl6 framework. In the CsAsCl6 framework, Cs1+ is bonded to six equivalent Cl1- atoms to form CsCl6 octahedra that share corners with six equivalent AsCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Cs–Cl bond lengths are 3.22 Å. As3+ is bonded to six equivalent Cl1- atoms to form AsCl6 octahedra that share corners with six equivalent CsCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All As–Cl bond lengths are 2.51 Å. Cl1- is bonded in a linear geometry to one Cs1+ and one As3+ atom.
