Figure 3
The crystal packing of (I), projected down the b axis, showing occlusion of the solvent molecules in the channel voids. H atoms have been omitted. The four porphyrin units in the upper layer are indicated by darker wireframe, while the six units of the lower layer are indicated by all-gray wireframe. Adjacent layers along b are related to each other by the screw/glide symmetry. The nitrobenzene solvent molecules are depicted as dotted atoms. |
