The SQUEEZE routine of PLATON was applied to remove the diffraction contribution from guests to give a set of solvent-free diffraction intensities. SQUEEZE estimated a total count of 124 electrons per unit cell. This corresponds with 124/4=31 electrons per asymmetric unit. As the formula unit is composed of 2 asymmetric units (Z = 2), this then implies that 62 electrons removed by SQUEEZE should be associated with the formula unit. As there are 10 electrons with a water molecule, the logical deduction is that some 6.2 water molecules should be added to the formula unit. The remaining solvent molecules were disordered and assigned as five H2O molecule according to the TGA and elemental analysis results, as the formula unit. This discrepancy might be owing to the moderate quality of low angle data caused by the highly disordered framework.

The following automatic conversions were performed:

'_symmetry_cell_setting' value 'Monoclinic' changed to 'monoclinic'
according to
/usr/data/users/saulius/crontab/automatic-downloads/rss-feeds/RSC/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.

'_exptl_crystal_density_meas' value 'none' was changed to '?' - the
value is perceived as not measured.
