Materials Data on Na2Ti2O5 by Materials Project
Na2Ti2O5 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Na1+ is bonded to four O2- atoms to form distorted NaO4 trigonal pyramids that share corners with five equivalent TiO4 tetrahedra, corners with four equivalent NaO4 trigonal pyramids, and an edgeedge with one NaO4 trigonal pyramid. There are a spread of Na–O bond distances ranging from 2.33–2.41 Å. Ti4+ is bonded to four O2- atoms to form TiO4 tetrahedra that share corners with three equivalent TiO4 tetrahedra and corners with five equivalent NaO4 trigonal pyramids. There are a spread of Ti–O bond distances ranging from 1.76–1.87 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Ti4+ atoms. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Na1+ and one Ti4+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Na1+ and two equivalent Ti4+ atoms.
