    • The number of links between the distal structure and the porphyrin, which was varied from three to four, was shown to have no detectable effect on the catalytic activity on the rotating electrode (see ref. [6]).

    • In the complex, the zinc atom, which is bound to an axial water molecule, is five-coordinate and lies 0.302(2) Å above the mean plane of the four nitrogen atoms, the porphyrin core being distorted in a saddle-shaped conformation. As shown in Figure 3, the axial water molecule, Ow5, is connected to the four arms through an H-bond network involving four other water molecules. It is noteworthy that this H-bond network ends either on two NH or on two oxygen atoms of the arms. Accordingly, the pickets exhibit different orientations: two of them have their NH groups pointing out of the macrocycle. while the other two have their carbonyl groups oriented towards the outside, thus allowing intermolecular H bonds between macrocycles (NH⋯OC). This observation is a good illustration of how a single water molecule, coordinated to the central metal, can influence the conformation of the structure tethered on the porphyrin.
