Figure 4
Projection drawings showing the π–π stackings in the (I)-monoclinic lattice: (a) viewed parallel to the porphyrin planes of (I), showing the four packing/stacking interactions to the porphyrin planes; (b) viewed perpendicular to the porphyrin plane of (I), showing adjacent parallel molecules with CH2⋯plane contacts; (c) viewed perpendicular to the porphyrin plane of (I), showing adjacent parallel molecules with Me⋯plane contacts. Atoms are represented by spheres of arbitrary radii. |
