Materials Data on Sr2RhF7 by Materials Project

Abstract

Sr2RhF7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Sr–F bond distances ranging from 2.39–2.99 Å. In the second Sr2+ site, Sr2+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of Sr–F bond distances ranging from 2.35–3.04 Å. Rh3+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Rh–F bond distances ranging from 2.00–2.04 Å. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded to three Sr2+ and one Rh3+ atom to form distorted corner-sharing FSr3Rh tetrahedra. In the second F1- site, F1- is bonded in a 4-coordinate geometry to three Sr2+ and one Rh3+ atom. In the third F1- site, F1- is bonded in a trigonal planar geometry to three Sr2+ atoms. In the fourth F1- site, F1- is bonded in a distorted trigonal planar geometry to two Sr2+ and one Rh3+ atom. In the fifth F1- site, F1- is bonded in a 3-coordinate geometry to two Sr2+ and one Rh3+ atom. In the sixth F1- site, F1- is bonded in a 1-coordinate geometry to three Sr2+ and one Rh3+ atom. In the seventh F1- site, F1- is bonded in a 1-coordinate geometry to three Sr2+ and one Rh3+ atom.
