The Platon Squeeze procedure was applied to recover 791 electrons per 
unit cell in two voids (total volume 2699 ^A^3); that is 197.75 electrons 
per formula unit. Disordered solvent lattice methanol molecules were 
present prior to the application of Squeeze, however, a satisfactory 
point atom model could not be achieved. The application of Squeeze gave 
a good improvement in the data statistics and allowed for a 
full anisotropic refinement of the  structure.
