Although there were several peaks within the void from Fourier difference map,
the highly disordered solvents within the void were
not crystallographically well defined.

The SQUEEZE routine of the program PLATON was used in order to eliminate
the contribution of disordered solvents molecules, thereby a final model
based only on the ordered part of the crystal structure was obtained.

The SQUEEZE routine suggested that a total
potential solvent area volume of 4807
Ang^3^[66.6% of cell volume], and a void electron population of 866 per cell.

Refinement after the SQUEEZE routine gave significantly improved R values.
