Approximately 69% of the unit cell volume comprises a large region of
disordered solvent which could not be modelled as discrete atomic sites.
We employed PLATON SQUEEZE to calculate the contribution to the diffraction
from the solvent region and thereby produced a set of solvent-free diffraction
intensities. SQUEEZE estimated a total count of 1252 electrons per unit cell.
The final formula including one dimethylammonium cation, one DMF, one MeCN
and four water molecules per indium complex anion, was calculated from the
SQUEEZE results combined with elemental analysis data.
