In the third Ti4+ site, Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.73–2.44 Å. In the fourth Ti4+ site, Ti4+ is bonded to six O2- atoms to form edge-sharing TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.92–2.07 Å. In the fifth Ti4+ site, Ti4+ is bonded to six O2- atoms to form edge-sharing TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.93–2.08 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Na1+ and three Ti4+ atoms. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Na1+ and three Ti4+ atoms. In the third O2- site, O2- is bonded to two Na1+ and three Ti4+ atoms to form distorted ONa2Ti3 trigonal bipyramids that share corners with two equivalent ONa2Ti3 trigonal bipyramids, edges with three ONa2Ti3 trigonal bipyramids, and an edgeedge with one ONaTi3 trigonal pyramid. In the fourth O2- site, O2- is bonded to two Na1+ and three Ti4+ atoms to form distorted ONa2Ti3 trigonal bipyramids that share corners with two equivalent ONa2Ti3 trigonal bipyramids, edges with three ONa2Ti3 trigonal bipyramids, and an edgeedge with one ONaTi3 trigonal pyramid. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to four Na1+ and one Ti4+ atom. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to four Na1+ and one Ti4+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti4+ atoms. In the eighth O2- site, O2- is bonded to one Na1+ and three Ti4+ atoms to form a mixture of distorted edge and corner-sharing ONaTi3 trigonal pyramids. In the ninth O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+ and two Ti4+ atoms. In the tenth O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+ and two Ti4+ atoms. In the eleventh O2- site, O2- is bonded to two Na1+ and three Ti4+ atoms to form distorted ONa2Ti3 trigonal bipyramids that share a cornercorner with one ONaTi3 trigonal pyramid and edges with four ONa2Ti3 trigonal bipyramids. In the twelfth O2- site, O2- is bonded to two Na1+ and three Ti4+ atoms to form distorted ONa2Ti3 trigonal bipyramids that share corners with two equivalent ONaTi3 trigonal pyramids and edges with four ONa2Ti3 trigonal bipyramids.
