Attempts to  model disordered solvent molecules
were unsuccessful. PLATON/SQUEEZE  was used to correct
the data for the presence of the disordered solvent.
A potential solvent volume of 1712.2 \%A^3^, 
63.9 % of the total unit-cell volume, was found.
710 electrons per unit cell worth of scattering were located
in the void. The reported structure is based on the 
PLATON/SQUEEZE corrected data. The actual solvent content is
unknown, so several quantities calculated like empirical formula, density, 
absorption coefficient, F(000) etc. may be incorrect.
