The formal exchange of the pyrrole units of porphyrin by bipyrrole units provides the title compound 1. The hexadecaethyl derivative of 1 is the only isolable product of a MacDonald condensation of tetrapyrrolic as well as of dipyrrolic components. The new cyclooctapyrrole adopts a figure-eight conformation in the solid state as well as in solution.
