The structure has a large volume fraction of solvent-accessible voids (33%
 of the unit cell volume) containing a number of residual electron density
 peaks attributable to lattice solvent molecules (water and DMF), which 
 were heavily disordered and could not be satisfactorily refined to
 a reasonable disorder model. Given that the refinement of the metal-organic
 coordination framework is essentially uninfluenced by the presence of the
 disordered solvent, the SQUEEZE routine in the PLATON software package
 [A.L. Spek, J. Appl. Crystallogr. 2003, 36, 7-13.] was applied to subtract
 the diffraction contribution from the solvent molecules.
