Materials Data on K4NaCl5 by Materials Project
Abstract
K4NaCl5 is Caswellsilverite-like structured and crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six Cl1- atoms to form KCl6 octahedra that share corners with six KCl6 octahedra, edges with four equivalent NaCl6 octahedra, and edges with eight KCl6 octahedra. The corner-sharing octahedra tilt angles range from 0–7°. There are a spread of K–Cl bond distances ranging from 3.09–3.17 Å. In the second K1+ site, K1+ is bonded to six Cl1- atoms to form KCl6 octahedra that share corners with two equivalent NaCl6 octahedra, corners with four KCl6 octahedra, an edgeedge with one NaCl6 octahedra, and edges with eleven KCl6 octahedra. The corner-sharing octahedra tilt angles range from 0–5°. There are a spread of K–Cl bond distances ranging from 3.15–3.21 Å. Na1+ is bonded to six Cl1- atoms to form NaCl6 octahedra that share corners with two equivalent NaCl6 octahedra, corners with four equivalent KCl6 octahedra, edges with two equivalent NaCl6 octahedra, and edges with ten KCl6 octahedra. The corner-sharing octahedra tilt angles range from 0–5°. There are four shorter (2.95 Å) and two longer (3.15 Å) Na–Cl bond lengths. There are threemore »
