Materials Data on Sb5O7F by Materials Project

Abstract

Sb5O7F is Antimony trioxide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two Sb5O7F sheets oriented in the (0, 1, 0) direction. there are five inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.00–2.63 Å. In the second Sb3+ site, Sb3+ is bonded in a 5-coordinate geometry to four O2- and one F1- atom. There are a spread of Sb–O bond distances ranging from 2.01–2.54 Å. The Sb–F bond length is 2.66 Å. In the third Sb3+ site, Sb3+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Sb–O bond distances ranging from 1.95–2.08 Å. In the fourth Sb3+ site, Sb3+ is bonded in a 4-coordinate geometry to three O2- atoms. There are a spread of Sb–O bond distances ranging from 1.98–2.05 Å. In the fifth Sb3+ site, Sb3+ is bonded in a rectangular see-saw-like geometry to three O2- and one F1- atom. There are a spread of Sb–O bond distances ranging from 2.05–2.10 Å. The Sb–F bond length is 2.20 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Sb3+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two Sb3+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to three Sb3+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to three Sb3+ atoms. In the fifth O2- site, O2- is bonded in a water-like geometry to two Sb3+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Sb3+ atoms. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to three Sb3+ atoms. F1- is bonded in a 1-coordinate geometry to two Sb3+ atoms.
