Porphyrins and their structural relatives-phthalocyanines and porphyrazines-constitute a distinct class of macrocyclic tetrapyrrolic systems with unique physico-chemical properties. Non-Uniformly 8,9,15,16,22,23-hexaphenyl-28H,30H-tripyrazino [5,6-b,g,l] imidazole [4,5-q] porphyrazinato-magnesium (an unsymmetrical porphyrazine) was prepared via mixed Linstead macrocyclization of 4,5-dicyanoimidazole and 2,3–dicyano–5,6–diphenylpyrazine. The structure of this material has been determined based on mass, FT-IR, UV-Vis and 1H NMR spectra and elemental analysis.
