During the refinement, the methanol molecules are
seriously disordered. During the final refinement,
the contribution of the solvent molecules to the crystal
structure is treated by using the Platon/SQUEEZE procedure.
Check using platon shows that there are 458\%A^3^ volumes
in the unit cell (approximately 84 electrons,
i.e. ca. 4.66 methanol molecules based on the solvents
we have used and each host molecule was
distributed 1.16 methanol molecules). So the suitable formula
should be C~38~H~37~N~5~O~9~.(MeOH)~1.16~. Some related items
have been corrected in the cif file.
