Materials Data on K4MnCl6 by Materials Project

Abstract

K4MnCl6 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six equivalent Cl1- atoms. There are four shorter (3.19 Å) and two longer (3.20 Å) K–Cl bond lengths. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six equivalent Cl1- atoms. All K–Cl bond lengths are 3.20 Å. Mn2+ is bonded in an octahedral geometry to six equivalent Cl1- atoms. All Mn–Cl bond lengths are 2.57 Å. Cl1- is bonded to four K1+ and one Mn2+ atom to form a mixture of distorted face and corner-sharing ClK4Mn square pyramids.
