During the refinement of the structure, electron density peaks were located
that were believed to be highly disordered
solvent molecules (possibly dichloromethane). Attempts
made to model the solvent molecule were not successful.
The SQUEEZE option in PLATON (Spek, 2003) indicated there was a
large solvent cavity. In the final cycles of refinement,
this contribution 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, 2003). 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).
