Materials Data on Sr3RhF12 by Materials Project
Sr3RhF12 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 4-coordinate geometry to four equivalent F atoms. All Sr–F bond lengths are 2.46 Å. In the second Sr site, Sr is bonded in a 8-coordinate geometry to eight F atoms. There are a spread of Sr–F bond distances ranging from 2.44–2.96 Å. Rh is bonded in a distorted body-centered cubic geometry to eight F atoms. There are four shorter (1.91 Å) and four longer (2.31 Å) Rh–F bond lengths. There are three inequivalent F sites. In the first F site, F is bonded in a distorted trigonal planar geometry to two Sr and one Rh atom. In the second F site, F is bonded in a 2-coordinate geometry to three equivalent Sr atoms. In the third F site, F is bonded in a single-bond geometry to one Rh atom.
