In the fifth Ti4+ site, Ti4+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of Ti–O bond distances ranging from 1.85–2.32 Å. In the sixth Ti4+ site, Ti4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ti–O bond distances ranging from 1.73–2.04 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.12 Å) and one longer (1.31 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.55 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two Ti4+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two Ti4+ atoms. In the third O2- site, O2- is bonded in a trigonal planar geometry to two Ti4+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ti4+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to two Ti4+ atoms.

In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ti4+ and one H1+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to three Ti4+ and one H1+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ti4+ atoms. In the eleventh O2- site, O2- is bonded to four Ti4+ atoms to form a mixture of distorted edge and corner-sharing OTi4 trigonal pyramids. In the twelfth O2- site, O2- is bonded to four Ti4+ atoms to form a mixture of distorted edge and corner-sharing OTi4 trigonal pyramids. In the thirteenth O2- site, O2- is bonded to four Ti4+ atoms to form a mixture of distorted edge and corner-sharing OTi4 trigonal pyramids. In the fourteenth O2- site, O2- is bonded in a 3-coordinate geometry to three Ti4+ atoms.
