;PROBLEM: VERY LARGE Solvent Accessible VOID(S) in Structure   ! 
RESPONSE: During the 
refinement of the structure, electron density peaks were located 
that were believed to be highly disordered 
solvent molecules (possibly bromobenzene). Attempts 
made to model the solvent molecule were not successful. 
The SQUEEZE option in PLATON (Spek, 2009) indicated there was a 
large solvent cavity 274.4 Ang^3. In the final cycles of refinement, 
this contribution (101) to the 
electron density was removed from the observed data. The 
density, the F(000) value, the molecular weight and the formula are 
given without taking into account the results obtained with the 
SQUEEZE option PLATON (Spek, 2009). Similar treatments of disordered 
solvent molecules were carried out by St\"ahler et al. (2001), 
Cox et al. (2003), Mohamed et al. (2003) and Athimoolam et al. (2005).
