Abstract
Na2PrO3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are seven inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.24–2.90 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.61 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share a cornercorner with one NaO4 trigonal pyramid and an edgeedge with one NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.32–2.64 Å. In the fourth Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.25–2.57 Å. In the fifth Na1+ site, Na1+ is bonded in a 3-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.86 Å. In the sixth Na1+ site, Na1+ is bonded to four O2- atoms to form distorted corner-sharing NaO4 trigonal pyramids.
