In the title complex, [Fe(C64H64N8O4)Cl]·0.5C6H5Cl·H2O, the equatorial iron–pyrrole N atom distance (Fe—Np) is 2.065 (2) Å and the axial Fe—Cl distance is 2.207 (2) Å. The iron cation is displaced by 0.420 (4) Å from the 24-atom mean plane of the porphyrin core. The asymmetric unit contains a quarter of an [FeIII(C64H64N8O4)Cl] complex molecule, with a fourfold rotation axis passing through the central metal cation and the Cl ligand, along with disordered molecules of chlorobenzene and water of solvation; the solvent molecules were excluded from the refinement
