1. Fixed Uiso
 At 1.2 times of:
  All C(H) groups
 At 1.5 times of:
  All C(H,H,H) groups
2.a Aromatic/amide H refined with riding coordinates:
 C13(H13), C9(H9), C3(H3), C11(H11), C5(H5), C4(H4)
2.b Idealised Me refined as rotating group:
 C15(H15A,H15B,H15C), C14(H14A,H14B,H14C)

All atoms are refined anisotropically and protons are generated 
in calculated positions and refined using the riding model. A 
421.5 Ang^3 solvent accessible void is present in the unit cell (~3.9%)
that corresponds to a total of 130 electrons. Attempts to model the disordered
THF molecules resulted in an unstable refinement of the model. The solvent mask
routine in OLEX 2 was used to remove this void for the final refinement.
