For the residual electron densities, only water O17 molecule
can be assigned unambiguously. For the other residual electron densities,
which should be considered as peaks from disordered water molecules,
did not give a chemical meaningful result after a carefull refinement.
Therefor, the contributions of the disordered
solvent molecules (c.a. 113 e/unit cell) were removed from the
diffraction data using the SQUEEZE routine of PLATON software and
then final refinements were carried out. These electon densities
account to ca. eleven water molecules, i.e. the
suitable moiety formula should be
Cu~2~C~58~H~50~N~16~.(Cl O~4~)~4~.(H~2~O)~6.5~ .
