The remaining solvent molecules were disordered and assigned as 16 DMF and 24 H2O molecules.
per unit cell, which were determined by TGA, elemental analysis and SQUEEZE results. 
The contributions of these disordered solvents to the scattering values have been removed 
by using the PLATON SQUEEZE program. We can see from the SQUEEZE that some 1059 electrons were 
removed from the unit cell, or some 1059/8 = 132 electrons per formula unit. This total includes 21 electrons 
from the hydrogen of the terminal coordinated DMF molecules in the backbone and other electrons (111 e) from 
disordered solvent, approximately 2 DMF (80 e) and 3 H2O (30 e) in the channel. From the calculation and
related information (The CHN and TGA), the formula unit should include 2 DMF and 3 H2O.
