WebConcomitant with the displacement of two N-H protons, porphyrins bind metal ions in the N4 "pocket".The metal ion usually has a charge of 2+ or 3+. A schematic equation for these syntheses is shown: H 2 porphyrin + [ML n] 2+ → M(porphyrinate)L n−4 + 4 L + 2 H +, where M = metal ion and L = a ligand.
