Materials Data on Na8Fe6P6(O8F3)3 by Materials Project
Abstract
Na8Fe6P6(O8F3)3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Na sites. In the first Na site, Na is bonded in a 7-coordinate geometry to four O and three F atoms. There are two shorter (2.42 Å) and two longer (2.44 Å) Na–O bond lengths. There are a spread of Na–F bond distances ranging from 2.36–2.54 Å. In the second Na site, Na is bonded in a 7-coordinate geometry to four O and three F atoms. There are two shorter (2.58 Å) and two longer (2.59 Å) Na–O bond lengths. There are two shorter (2.41 Å) and one longer (2.64 Å) Na–F bond lengths. In the third Na site, Na is bonded in a 7-coordinate geometry to four O and three F atoms. There are a spread of Na–O bond distances ranging from 2.39–2.69 Å. There are a spread of Na–F bond distances ranging from 2.49–2.57 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to four O and two F atoms to form FeO4F2 octahedra that share a cornercorner with one FeO4F2 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 5°. Theremore »
