Approximately 13% of the unit cell volume comprises a large region of
disordered solvent which could not be modeled as discrete atomic sites.
We employed PLATON SQUEEZE to calculate the contribution to the diffraction
from the solvent region and thereby produced a set of solvent-free diffraction
intensities. SQUEEZE estimated a total count of 177 electrons per unit cell.
According to the final formula which was calculated from TGA combined with 
elemental analysis data, these electrons were assigned to be 4 acetonitrile and 
4 water molecules per unit cell.
