Title: Materials Data on Fe4P2N3O8F9 by Materials Project

Abstract

(Fe4P2O8F9)2(N2)3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional and consists of six ammonia molecules and one Fe4P2O8F9 framework. In the Fe4P2O8F9 framework, there are three inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to two O2- and four F1- atoms to form FeO2F4 octahedra that share corners with three FeO2F4 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 34–38°. There are one shorter (2.02 Å) and one longer (2.03 Å) Fe–O bond lengths. There are a spread of Fe–F bond distances ranging from 1.83–2.00 Å. In the second Fe3+ site, Fe3+ is bonded to two equivalent O2- and four F1- atoms to form FeO2F4 octahedra that share corners with four FeO2F4 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 37–46°. Both Fe–O bond lengths are 2.01 Å. There are a spread of Fe–F bond distances ranging from 1.94–1.97 Å. In the third Fe3+ site, Fe3+ is bonded to two equivalent O2- and four F1- atoms to form FeO2F4 octahedra that share corners with four FeO2F4 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles rangemore » from 38–46°. Both Fe–O bond lengths are 1.99 Å. There is two shorter (1.95 Å) and two longer (1.97 Å) Fe–F bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 38–46°. There is two shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Fe3+ and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Fe3+ and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Fe3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Fe3+ and one P5+ atom. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Fe3+ atom. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Fe3+ atoms. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to two Fe3+ atoms. In the fourth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two Fe3+ atoms. In the fifth F1- site, F1- is bonded in a bent 150 degrees geometry to two Fe3+ atoms. In the sixth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Fe3+ atoms.« less
