PLATON/SQUEEZE was used to treat two Ethanol and one Methanol molecules in the asymmetric unit. These were removed from the model, but included in the empirical formula.
PLATON / Squeeze results (Spek, 2009):
Total Potential Solvent Area Vol 1430.7 Ang^3
per Unit Cell Vol 8650.2 Ang^3 [16.5%]
Total Potential Solvent Accessible Void Vol: 1430.7 Ang^3
Electron Count / Cell = 267 - To be included in D(calc), F000 & Mol.Wght.
Correction - Since two Ethanol and one Methanol with electron count = 70 were removed, then 70 electron will be added into F000. The empirical formula is correct.
