During the structure solution, electron density difference 
maps revealed that there were considerable disordered 
solvent molecules which could not be successfully modeled.  
From history, the remaining solvate was likely pentane in 
a volume of 261.8 \%A3 per unit cell (11.2%).  It appeared 
that the cavity area contained about one pentane molecule, 
located near the center of symmetry at (1/2, 1/2, 0). 
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 38 e- per unit 
cell, likely representing one pentane molecule, consistent 
with our earlier observations.  Use of the SQUEEZE 
technique resulted in a decrease of ca. 2.3 % in R.
