Materials Data on Sr4RhO6 by Materials Project
Sr4RhO6 crystallizes in the trigonal R-3c 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 equivalent O2- atoms. There are a spread of Sr–O bond distances ranging from 2.61–2.80 Å. In the second Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Sr–O bond lengths are 2.47 Å. Rh4+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Rh–O bond lengths are 2.08 Å. O2- is bonded to five Sr2+ and one Rh4+ atom to form a mixture of distorted corner, edge, and face-sharing OSr5Rh octahedra. The corner-sharing octahedra tilt angles range from 0–63°.
