(a) Fragments of the reconstructed 0kl reciprocal-lattice slice for β-NH4[(MeO)2cDHAP] at different temperatures, showing the changes in the unit-cell symmetry and dimensions. (b) View of the unit cells at different temperatures, projected along the a-axis. (c) Symmetry elements in monoclinic phases: HTP (shown in grey) and MTP (grey and red). (d) Triclinic phases: (pseudo)symmetry elements present in RTP and LTP are shown in black and blue, respectively; those present in both are red (local non-crystallographic pseudosymmetry – transparent lines and numbers).
