The solvent molecules in the structure were highly disordered. Efforts to 
locate and refine the solvent peaks were in vain. The SQUEEZE routine was
used to remove the scattering from the highly disordered solvent molecules,
the 626 electrons can be accounted for by 15.65 (i.e. ~16) water molecules 
per formula unit, and the reported formula, formula weight, density, F(000),
etc. include the solvents.
