Materials Data on Fe7Sb10(Br4O9)2 by Materials Project
Abstract
Fe7Sb10(O9Br4)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Fe7Sb10(O9Br4)2 sheet oriented in the (1, 0, 1) direction. there are four inequivalent Fe+2.86+ sites. In the first Fe+2.86+ site, Fe+2.86+ is bonded in a distorted octahedral geometry to three O2- and three Br1- atoms. There are two shorter (2.13 Å) and one longer (2.24 Å) Fe–O bond lengths. There are a spread of Fe–Br bond distances ranging from 2.65–2.87 Å. In the second Fe+2.86+ site, Fe+2.86+ is bonded in a 6-coordinate geometry to four O2- and two Br1- atoms. There are a spread of Fe–O bond distances ranging from 2.06–2.24 Å. There are one shorter (2.67 Å) and one longer (3.10 Å) Fe–Br bond lengths. In the third Fe+2.86+ site, Fe+2.86+ is bonded in a 4-coordinate geometry to four O2- and two Br1- atoms. There are a spread of Fe–O bond distances ranging from 2.06–2.22 Å. There are one shorter (2.87 Å) and one longer (2.92 Å) Fe–Br bond lengths. In the fourth Fe+2.86+ site, Fe+2.86+ is bonded in a distorted linear geometry to two equivalent O2- and four Br1- atoms. Both Fe–O bond lengths are 1.95 Å. There are two shorter (2.75more »
