Title: Materials Data on NaFeSO4F by Materials Project

Abstract

NaFeSO4F crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to six O2- and one F1- atom. There are a spread of Na–O bond distances ranging from 2.45–2.90 Å. The Na–F bond length is 2.20 Å. Fe2+ is bonded to four O2- and two equivalent F1- atoms to form FeO4F2 octahedra that share corners with two equivalent FeO4F2 octahedra and corners with four equivalent SO4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. There are two shorter (2.20 Å) and two longer (2.22 Å) Fe–O bond lengths. Both Fe–F bond lengths are 2.00 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent FeO4F2 octahedra. The corner-sharing octahedra tilt angles range from 36–50°. There is two shorter (1.49 Å) and two longer (1.50 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Fe2+, and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Fe2+, and one S6+ atom. F1- is bonded in a trigonal planarmore » geometry to one Na1+ and two equivalent Fe2+ atoms.« less
