In the fourth V+4.67+ site, V+4.67+ is bonded to five O2- atoms to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.65–1.98 Å. In the fifth V+4.67+ site, V+4.67+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with two equivalent VO6 octahedra and a cornercorner with one VO5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 30°. There are a spread of V–O bond distances ranging from 1.66–2.21 Å. In the sixth V+4.67+ site, V+4.67+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.62–2.35 Å. There are fifteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Na1+ and one V+4.67+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to four V+4.67+ atoms.
