The uncoordinated N-donor ligands were highly disordered and could not be 
modeled properly, thus the SQUEEZE routine of PLATON was applied 
to remove the contributions to the scattering from the ligand 
molecules. The reported refinements are of the guest-free structures 
using the *.hkp files produced via the SQUEEZE routine.  
These ligand molecules (one quarter of 2-npy and one point two five
 water molecules) were directly included in the final 
molecular formula based on the elemental analysis and SQUEEZE analyses.
