Di-aqua-[5,10,15,20-tetra-kis-(4-chloro-phen-yl)porphyrinato-κ(4) N]iron(III) tri-fluoro-methane-sulfonate-4-hy-droxy-3-meth-oxy-benzaldehyde-water (1/1/2).

In the title compound, [Fe(C44H24Cl4N4)(H2O)2](SO3CF3)·C8H8O3·2H2O, the Fe(III) cation is chelated by the four N atoms of the deprotonated tetra-kis-(4-chloro-tetra-phen-yl)porphyrin (TClPP) and further coordinated by two water mol-ecules in a distorted octa-hedral geometry. In the crystal, the cations, anions, 4-hy-droxy-3-meth-oxy-benzaldehyde and water mol-ecules of crystallization are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O and C-H⋯Cl hydrogen bonds into a three-dimensional supra-molecular architecture. The crystal packing is further stabilized by weak C-H⋯π inter-actions involving pyrrole and benzene rings. π-π stacking between parallel benzene rings of adjacent 4-hy-droxy-3-meth-oxy-benzaldehyde mol-ecules is also observed, the centroid-centroid distance being 3.8003 (13) Å. The three F atoms of the anion are disordered over two sets of sites, with a refined occupancy ratio 0.527 (12):0.473 (12). The O atom of one water mol-ecule of crystallization is also disordered over two positions in an occupancy ratio of 0.68 (5):0.32 (5).
