The Platon Squeeze procedure was applied to recover 1717 electrons per
unit cell in seven voids (total volume 7459 ^A^3); that is 143 electrons
per formula unit (with Z=12). Disordered lattice solvent methanol
(approx. 3) and water molecules (approx. 8) were present prior to the
application of Squeeze, however, a good point atom model could not be
achieved. Additionally, in order for the charge of the 0.25-occupancy
[Ni(H2O)6] cation to be balanced, a 0.5-occupancy hydroxide molecule must
additionally be present. The application of Squeeze gave a good
improvement in the data statistics and allowed for a full anisotropic
refinement of the structure.
