porphyrins adopted very distorted nonplanar structures in the crystalline state. In the crystalstructure of 3 the pyrrole rings were tilted with respect to the mean plane of the porphyrin to give a saddle conformation, whereas in the crystalstructure of the nickel(II) complex of 4c (Ni4c) the pyrrole rings were twisted with respect to the mean plane to give a ruffled conformation. Nonplanar conformations with
