Table 1668. P2/c (13) space group.
Figure 1668 shows a selected area electron diffraction (SAED) pattern of an Bi12.8Co0.2Mo5O34±δ crystal taken along [010] and [100] zone axes. The forbidden reflections still appeared due to double diffraction. However, this effect disappeared when the crystal was tilted away from the perfect zone axis orientation. The weak lines of the diffuse scattering along the c* direction (e.g. marked by the red arrow) indicated the presence of atomic disordering of this crystal structure.
