The disordered solvent molecules cannot be modeled and were treated 
by SQUEEZE,PLATON.
There are total 1107e per unit cell were accumulated which corresponds 
to 276e per formula(C96H94Co4N7O12). The 276e might come from a 
mixture of water and methanol molecules and were not included in the formula.
