The Platon SQUEEZE procedure was applied to recover 141 electrons per
unit cell in one void (total volume 22228 ^A^3); that is 517 electrons
per formula unit. Lattice solvent water molecules (10 electrons/H2O) and
N,N-Dimethylacetamide (48 electrons/DMA) were present, and the electrons
recovered by SQUEEZE have been assigned as 13 water molecules and 8 DMA
molecules per formula unit. These water molecules have been included
in the formula for the calculation of intensive properties.
