There are four shorter (1.98 Å) and two longer (2.08 Å) Rh–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Rh4+ atoms to form a mixture of distorted face, edge, and corner-sharing OSr4Rh2 octahedra. The corner-sharing octahedra tilt angles range from 0–55°. In the second O2- site, O2- is bonded to five equivalent Sr2+ and one Rh4+ atom to form distorted OSr5Rh octahedra that share corners with seventeen OSr4Rh2 octahedra, edges with eight equivalent OSr5Rh octahedra, and faces with four equivalent OSr4Rh2 octahedra. The corner-sharing octahedra tilt angles range from 0–55°.
