;
Big solvent Voids are obtained during the first 
modelling of the data, due to non-localised solvent molecules. 
In order to get an idea of how many solvent molecules occupies the 
empty space, a SQUEZZE procedure was performed. A total of 918 
electron counts were found, which were attributed to a total of 
22 molecules of isobutanol (42 electron counts per molecule). 
These molecules have been added to the molecular formula in the cif file
and not to the _chemical_formula_sum.
