N2 - Crystallographic analysis of three TiO2 structures shows that all of them have a rhombohedral anion sublattice close to their cubic closest packing. In brookite it competes with the hexagonal packing, and the packing of TiO6 octahedra is less regular. High symmetry of anatase and rutile is initiated by the local (cubic) symmetry of TiO6 octahedra. Cations occupy most symmetrical special positions and provide a coherent assembly of these “building units” by spreading the local symmetry over the entire structure.
