In the second Rh+3.29+ site, Rh+3.29+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are a spread of Rh–O bond distances ranging from 2.02–2.06 Å. In the third Rh+3.29+ site, Rh+3.29+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Rh–O bond distances ranging from 2.03–2.07 Å. In the fourth Rh+3.29+ site, Rh+3.29+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are a spread of Rh–O bond distances ranging from 2.04–2.06 Å. In the fifth Rh+3.29+ site, Rh+3.29+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are two shorter (2.04 Å) and four longer (2.05 Å) Rh–O bond lengths. In the sixth Rh+3.29+ site, Rh+3.29+ is bonded to six O2- atoms to form a mixture of corner and face-sharing RhO6 octahedra. The corner-sharing octahedra tilt angles range from 54–56°.
