In organometallic chemistry, transition metal porphyrin complexes are a family of coordination complexes of the conjugate base of porphyrins. Iron porphyrin complexes occur widely in nature, which has
Side view of Fe(OEP)CS (ethyl groups removed for clarity), showing the highly planar nature of the porphyrin ring. In this case, Fe is elevated by 0.23 Å above the N4 plane. In the related Fe(OEP)CS(pyridine) complex, the FeN4 groups are coplanar.
(a) An example structure of a porphyrin derivative molecule. (b) On a gold surface, deposition of Co induces the formation of flexible 1D porphyrin coordination polymers with defined chains and clusters. Each rosette cluster in (c-d) contains 4 or 5 molecules in the core and 8 or 10 molecules in the outer shells (STM images). Blue and green bars in (c-d) indicate two different structural isomers present within the rosette.
An example of porphyrins involved in host–guest chemistry. Here, a four-porphyrin–zinc complex hosts a porphyrin guest.

Porphyrins are heterocyclic, macrocyclic, organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges, so they are cyclic tetrapyrroles. In
