During the structure solution, electron density difference 
maps revealed that there was considerable disordered 
associated with a DCM solvent molecule, which could not 
be successfully modeled.  From history, the remaining 
solvate was likely DCM in a volume of 155.7 \%A3 per unit 
cell (4.7%).  It appeared that the cavity area contained 
about one DCM molecule, located near an inversion center 
at (0, 0, 1/2), as shown in the bc projection below. 
Modeling with or without restraints was unsuccessful, 
as was step by step acquisition of peaks using successive 
electron density difference maps.  Thus, the structure 
factors were modified using the PLATON SQUEEZE, technique, 
in order to produce a "solvate-free" structure factor set.  
PLATON reported a total electron density of 34 e- per unit 
cell, likely representing one DCM molecule, consistent 
with our earlier observations.  Use of the SQUEEZE 
technique resulted in a decrease of ca. 2.7 % in R.
