Squeeze results are consistent with a molecule of THF disordered about a 
special position.  Modeling using the PART -1 command was attempted but
the model would not survive refinement with chemically reasonable bond
lengths and angles.  The solvent is not interacting with the cation or anion
so it was removed and the empirical formula altered to include this solvent.
