Large sections of the structure, 449.1 cubic Angstrom or 45.8% of 
the unit cell volume, consist of solvent filled voids. The content 
of the voids is partially recognizable as mostly disordered 
dimethylacetamide, isopropanol, and some water molecules, while 
other sections show only featureless electron density. Attempts 
to include solvent molecules in the structural model yielded less 
than satisfactory results. The data were thus instead corrected for 
using back Fourier transform methods as implemented in the Squeeze 
algorithm of the Platon program package. Correction for unresolved 
electron density yielded 130 electrons for the void volume.
