Atoms Per Unit Cell of Anatase TiO2

Not what you're looking for?

Ask Custom Question

Anatase TiO2 has 12 atoms per unit cell (four TiO2 units). However, I'm having trouble differentiating the placement of the atoms (e.g. corner, edge, face, etc), so I'm not sure how to count all 12. Please describe how there are 12 atoms in the anatase unit cell, specifically indicating the contributions (number and contribution of face, edge, corner, etc.). The unit cell can be found here:
