Approximately 14.7% of the unit cell volume comprises a large region of
disordered solvent which could not be modelled as discrete atomic sites.
We employed PLATON SQUEEZE to calculate the contribution to the diffraction
from the solvent region and thereby produced a set of solvent-free diffraction
intensities. SQUEEZE estimated a total count of 43 electrons in a large void, 
which was assigned to be a CH2Cl2 molecule per unitcell.
