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 681.5 Ang^3^[31.1% of cell volume],
and a void electron population of 109 per cell.

Refinement after the SQUEEZE routine gave significantly improved R values.
