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 10442.8 Ang^3^[54.2% of cell volume].

Refinement after the SQUEEZE routine gave significantly improved R values.
