Owing to the serious crystal deterioration, although the crystals
selected were sealed in capillaries with mother liquid, the non-coordinated
solvent molecules could not be modeled by discrete atoms. Then
the contribution of the solvent to the diffraction pattern was subtracted
using the SQUEEZE procedure in PLATON. The result indicated that the
solvent-accessible void in the unit cell has a volume of 626\%A^3^.
(consisting of about 32% of the crystal volume). The residual electron
density count amounted to 107 e per unit cell, i.e. every
Cu(NTB)(ClO~4~)~2~ molecule being distributed
with 53.5 electrons, corresponding to nearly two methanol and two water
molecules (as the crystals were grown in the mixture of methanol
and water solvent.). The formula of the title complex should be
Cu(NTB)(ClO~4~)~2~(CH~3~OH)~2~(H~2~O)~2~.
