Materials Data on MnFe2Pb8F24 by Materials Project
Abstract
MnFe2Pb8F24 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mn2+ is bonded to six F1- atoms to form MnF6 octahedra that share corners with four equivalent FeF6 octahedra. The corner-sharing octahedra tilt angles range from 27–34°. There are a spread of Mn–F bond distances ranging from 2.10–2.20 Å. Fe3+ is bonded to six F1- atoms to form FeF6 octahedra that share corners with two equivalent MnF6 octahedra. The corner-sharing octahedra tilt angles range from 27–34°. There are a spread of Fe–F bond distances ranging from 1.95–2.00 Å. There are four inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Pb–F bond distances ranging from 2.36–2.89 Å. In the second Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Pb–F bond distances ranging from 2.40–2.62 Å. In the third Pb2+ site, Pb2+ is bonded in a 7-coordinate geometry to seven F1- atoms. There are a spread of Pb–F bond distances ranging from 2.46–2.83 Å. In the fourth Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spreadmore »
