Figure 2
Measured reflections (Cu radiation) plotted in the reciprocal space viewed along a* (in the correct cell choice) showing alternate layers of strong and weak reflections. If weak reflections are omitted, a smaller unit cell is obtained (cell choice II, corresponding reciprocal-lattice parameter c′* shown). If all reflections are used, the correct unit cell is obtained (cell choice I, corresponding reciprocal-lattice parameter c* shown). The central layer (hk0) also shows systematic absences (k odd) indicating the presence of an a-glide plane.
