Materials Data on CaMnF5 by Materials Project
Abstract
CaMnF5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ca2+ is bonded to seven F1- atoms to form CaF7 pentagonal bipyramids that share corners with four equivalent MnF6 octahedra, edges with two equivalent MnF6 octahedra, and edges with two equivalent CaF7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 2–38°. There are a spread of Ca–F bond distances ranging from 2.25–2.53 Å. Mn3+ is bonded to six F1- atoms to form MnF6 octahedra that share corners with two equivalent MnF6 octahedra, corners with four equivalent CaF7 pentagonal bipyramids, and edges with two equivalent CaF7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 35°. There are a spread of Mn–F bond distances ranging from 1.86–2.10 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to one Ca2+ and two equivalent Mn3+ atoms. In the second F1- site, F1- is bonded in a linear geometry to one Ca2+ and one Mn3+ atom. In the third F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one Mn3+ atom.
