The solvent masking procedure as implemented in Olex2 was used to remove the
electronic contribution of solvent molecules from the refinement.  Only the
atoms used in the refinement model are reported in the formula here.

Total solvent accessible volume / cell = 2191.4 Ang^3^ [46.0%]
Total electron count / cell = 496.1
