Materials Data on TiO2 by Materials Project
TiO2 crystallizes in the orthorhombic Cmm2 space group. The structure is two-dimensional and consists of one TiO2 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded in a distorted single-bond geometry to five O2- atoms. There are a spread of Ti–O bond distances ranging from 1.63–2.09 Å. In the second Ti4+ site, Ti4+ is bonded to four O2- atoms to form corner-sharing TiO4 tetrahedra. There is two shorter (1.81 Å) and two longer (1.87 Å) Ti–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ti4+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one Ti4+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ti4+ atoms.
