Highly Disordered solvent (DMA and H~2~O) molecules were not determined
and the contributions of these disordered solvent molecules to 
the scattering values have been removed by using the PLATON SQUEEZE 
program. TGA and elemental analyses reveal that it contains one DMA and 
3.5 water molecules per molecular unit. Then, the formula can be get 
as [Zn(C~18~H~12~N~6~O~4~)]DMA.3.5H~2~O.
