Figure 2
A stereoview of the hydrogen-bonding interaction scheme in (I). H atoms have been omitted, except for those involved in the hydrogen bonds. The Zn, N and O atoms are shown as darkened spheres. For clarity, the nitrobenzene solvent molecules have been excluded. Note the chain connectivity of the (COOH)2 hydrogen-bonded porphyrin dimers [centered at (, , )] along the vertical direction. |
