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, 724 
in four voids per unit cell, is included in the formula, 
formula weight, calculated density, and F(000). There are 
four formula units in one unit cell. On base of charge 
balance considerations, volume/count_electrons analysis, 
TG analyses and elemental analyses, this residual electron density 
was assigned to five molecules of ethanol, and five molecules of water. 
So SQUEEZE removed these disordered units per unit cell. 
The tentative formula for compound 2 is presented as in the text.
