Iron(tetraporphyrinato) chloride is the coordination complex with the formula Fe(TPP)Cl where TPP is the dianion [C<sub>44</sub>H<sub>28</sub>N<sub>4</sub>]<sup>2-</sup>. The compound forms blue microcrystals that dissolve in chlorinated solvent to give brown solutions. In terms of structure, the complex is five-coordinate with idealized C<sub>4v</sub> point group symmetry. It is one of more common transition metal porphyrin complexes.
Fe(TPP)Cl is prepared by the reaction of tetraphenylporphyrin (H<sub>2</sub>TPP) and ferrous chloride in the presence of air:
The chloride can be replaced with other halides and pseudohalides. Base gives the "mu-oxo dimer":
Most relevant to catalysis, the complex is easily reduced to give ferrous derivatives (L = pyridine, imidazole):
The complex is widely studied as a catalyst.
