2.1.4. S3CHCl3-H2O

CHCl3 (2.3 mL) was added to 330 mg of BL at 60 ◦C. The solution was cooled down overnight and left in the fridge (4–5 ◦C) for four days until single crystal growing. This solvate was stable in the mother liquor. The single crystal was analyzed by SCXRD at low temperature to prevent its transformation into form SCHCl3-H2O.
