Materials Data on Sr6(RhO3)5 by Materials Project
Sr6(RhO3)5 crystallizes in the trigonal R32 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.56–2.95 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.48–2.85 Å. There are three inequivalent Rh+3.60+ sites. In the first Rh+3.60+ site, Rh+3.60+ is bonded to six O2- atoms to form face-sharing RhO6 octahedra. All Rh–O bond lengths are 2.06 Å. In the second Rh+3.60+ site, Rh+3.60+ is bonded to six O2- atoms to form face-sharing RhO6 octahedra. There are three shorter (2.02 Å) and three longer (2.10 Å) Rh–O bond lengths. In the third Rh+3.60+ site, Rh+3.60+ is bonded to six equivalent O2- atoms to form distorted face-sharing RhO6 octahedra. All Rh–O bond lengths are 2.07 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted see-saw-like geometry to two Sr2+ and two Rh+3.60+ atoms. In the second O2- site, O2- is bonded to four Sr2+ and two equivalent Rh+3.60+ atoms to form a mixture of distorted corner and face-sharing OSr4Rh2 octahedra. The corner-sharing octahedral tilt angles are 27°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to four Sr2+ and two Rh+3.60+ atoms.
