Approximately 38.4 % of the unit cell volume comprises a large region of disordered solvent that could not be modeled 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 1309.7 electrons per unit cell which were assigned to 13 EtOH molecules per cluster.
