The EXYZ and EADP constraint is used to make C7 and N1, C7' and N1'at same position with same temperature factor. Considering crystal symmetry, C7 and C7' have occupancy of 0.375; N1 and N' have occupancy of 0.125. ISOR were used to C7, N1, C7' and N1' atoms, which restained these atom to be approximately isotropic.  
Reflections were merged by SHELXL according to the crystal
 class for the calculation of statistics and refinement.
 
 _reflns_Friedel_fraction is defined as the number of unique
 Friedel pairs measured divided by the number that would be
 possible theoretically, ignoring centric projections and
 systematic absences.

 All esds (except the esd in the dihedral angle between two l.s. planes)
 are estimated using the full covariance matrix.  The cell esds are taken
 into account individually in the estimation of esds in distances, angles
 and torsion angles; correlations between esds in cell parameters are only
 used when they are defined by crystal symmetry.  An approximate (isotropic)
 treatment of cell esds is used for estimating esds involving l.s. planes.

Approximately 66.9% of the unit cell volume comprises a large region of disordered solvent which could not be modelled as discrete atomic sites. We employed PLATON SQUEEZE to calculate the contribution to the diffraction from the solvent region and thereby produced a set of solvent-free diffraction intensities. SQUEEZE estimated a total count of 1125 electrons per unit cell.
The final formula was calculated from the SQUEEZE results combined with elemental anylysis and TGA data.
