_platon_squeeze_details
;Platon squeeze was used to remove a total of 354 total electons
from a single solvent accessible void. Only one of two perchlorate counter ions could be found from the difference map. Removal of the second ClO4- results in the removal of 98 e- from the cell. As the crystals were grown from DMSO and contain two well ordered DMSO solvate molecules it is assumed the remaining disordered solvet squeezed from the model correspond to additional DMSO solvate molecules. Given the remaining 256 e- squeezed from the cell this corresponds to 6 addtional DMSO molecules per cell or 3 per Zn complex. The sum and moiety formulas and corresponding values reflect these additions.
