Approximately 10.4% of the unit cell volume comprises
a region of disordered solvent which could not be 
modelled as discrete atomic sites.  We employed PLATON 
SQUEEZE to calculate the solvent contribution to the 
diffraction.  SQUEEZE estimated a total of 188 electrons
per unit cell associated with FOUR molecules of 
CH2Cl2, and thereby produced a set of solvent-free
diffraction intensities.
