Figure 3
A slice of the structure of (I[link]) parallel to the ab plane, emphasizing the additional porphyrin–crown-ether hydrogen bonding through an axial methanol ligand in a direction perpendicular to the porphyrin plane. Also illustrated is the stacked organisation of the layers shown in Fig. 2[link]. This slice of the structure is sandwiched above and below between sections consisting of stacked crown-ether moieties only (see Fig. 4[link]), accounting for the 1:3 ratio between the porphyrin and crown-ether components. Note the slight deviation of the ZnII ion from the porphyrin core towards the axial ligand.
