Title: Materials Data on KNbCl6 by Materials Project

Abstract

KNbCl6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 12-coordinate geometry to twelve Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.40–3.94 Å. In the second K1+ site, K1+ is bonded to twelve Cl1- atoms to form KCl12 cuboctahedra that share corners with three KCl12 cuboctahedra, faces with four KCl12 cuboctahedra, and faces with four NbCl6 octahedra.
