During the structure solution, electron density 
difference maps revealed that there were considerable 
disordered solvent molecules.  Two ether molecules were 
refined using distance, angle, and thermal similarity 
restraints.  Additional electron density corresponding 
to further disordered solvent could not be successfully 
modeled.  From history, the remaining solvate was likely 
ether in a volume of 1016.7 \%A3 per unit cell (7.9%).  
It appeared that the cavity area contained about two ether
 molecules, located near the centers of symmetry at 
(0, 1/2, 0) and (0, 0, 1/2). 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 (only for the third independent molecule).  
PLATON reported a total electron density of 92 e- per unit 
cell, likely representing two ether molecules, consistent 
with our earlier observations.  Use of the SQUEEZE technique 
resulted in a decrease of ca. 0.7 % in R.
