The PLATON SQUEEZE procedure was used to treat 
regions of diffuse solvent which could not be modeled 
properly in terms of atomic sites. Their contribution to 
the diffraction pattern was removed and modified F^2^ was
written to a new HKL file. The number of located electrons, 
in one void per unit cell is 221.There are eight formula units 
in one unit cell. On base of charge balance considerations, volume/count_electrons 
analysis, elemental analyses, this residual electron density 
was assigned to one [NH2(CH3)2]+. 
So SQUEEZE removed these disordered units per unit cell.
