Materials Data on K2SnCl6 by Materials Project
K2SnCl6 crystallizes in the tetragonal P4/mnc space group. The structure is three-dimensional. K1+ is bonded to twelve Cl1- atoms to form KCl12 cuboctahedra that share corners with twelve equivalent KCl12 cuboctahedra, faces with six equivalent KCl12 cuboctahedra, and faces with four equivalent SnCl6 octahedra. There are a spread of K–Cl bond distances ranging from 3.49–3.72 Å. Sn4+ is bonded to six Cl1- atoms to form SnCl6 octahedra that share faces with eight equivalent KCl12 cuboctahedra. There are two shorter (2.46 Å) and four longer (2.47 Å) Sn–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four equivalent K1+ and one Sn4+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four equivalent K1+ and one Sn4+ atom.
