Title: Materials Data on K2Mn(NbCl3)6 by Materials Project

Abstract

K2Mn(NbCl3)6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. K1+ is bonded to twelve Cl1- atoms to form KCl12 cuboctahedra that share corners with three equivalent MnCl6 octahedra, corners with six equivalent NbCl5 square pyramids, edges with three equivalent KCl12 cuboctahedra, edges with three equivalent NbCl5 square pyramids, and faces with three equivalent NbCl5 square pyramids. The corner-sharing octahedral tilt angles are 51°. There are a spread of K–Cl bond distances ranging from 3.49–3.55 Å. Nb+2.33+ is bonded to five Cl1- atoms to form NbCl5 square pyramids that share corners with two equivalent KCl12 cuboctahedra, a cornercorner with one MnCl6 octahedra, corners with four equivalent NbCl5 square pyramids, an edgeedge with one KCl12 cuboctahedra, and a faceface with one KCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of Nb–Cl bond distances ranging from 2.47–2.67 Å. Mn2+ is bonded to six equivalent Cl1- atoms to form MnCl6 octahedra that share corners with six equivalent KCl12 cuboctahedra and corners with six equivalent NbCl5 square pyramids. All Mn–Cl bond lengths are 2.61 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 3-coordinate geometry to one K1+ andmore » two equivalent Nb+2.33+ atoms. In the second Cl1- site, Cl1- is bonded in a 2-coordinate geometry to one K1+, one Nb+2.33+, and one Mn2+ atom. In the third Cl1- site, Cl1- is bonded in a 4-coordinate geometry to two equivalent K1+ and two equivalent Nb+2.33+ atoms.« less
