Figure 2
Projection along b of (a) a parent structure of rutile, (b) rutile blocks and (c) the CS structure of Ga4Tim−4O2m−2. Removal of atoms in the vicinity of the shear planes from the rutile structure of (a) gives rutile blocks in (b). The displacement of the rutile blocks by the shear vector completes the CS operation, resulting in the CS structure of (c). |
