description: NaRh2C5H9O12 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one NaRh2C5H9O12 sheet oriented in the (-1, 0, 2) direction. Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share edges with two RhO5 square pyramids. There are a spread of Na–O bond distances ranging from 2.32–2.56 Å. There are two inequivalent Rh4+ sites. In the first Rh4+ site, Rh4+ is bonded to five O2- atoms to form RhO5 square pyramids that share an edgeedge with one NaO6 octahedra. There are a spread of Rh–O bond distances ranging from 2.06–2.28 Å. In the second Rh4+ site, Rh4+ is bonded to five O2- atoms to form RhO5 square pyramids that share an edgeedge with one NaO6 octahedra. There are a spread of Rh–O bond distances ranging from 2.05–2.34 Å. There are five inequivalent C+1.20+ sites. In the first C+1.20+ site, C+1.20+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å.
