Di­aqua­[5,10,15,20-tetra­kis­(4-chloro­phen­yl)porphyrinato-κ(4) N]iron(III) tri­fluoro­methane­sulfonate–4-hy­droxy-3-meth­oxy­benzaldehyde–water (1/1/2)

In the title compound, [Fe(C(44)H(24)Cl(4)N(4))(H(2)O)(2)](SO(3)CF(3))·C(8)H(8)O(3)·2H(2)O, the Fe(III) cation is chelated by the four N atoms of the deprotonated tetra­kis­(4-chloro­tetra­phen­yl)porphyrin (TClPP) and further coordinated by two water mol­ecules in a distorted octa­hedral geometry. In the crystal, the cations, anions, 4-hy­droxy-3-meth­oxy­benzaldehyde and water mol­ecules 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 supra­molecular architecture. The crystal packing is further stabilized by weak C—H⋯π inter­actions involving pyrrole and benzene rings. π–π stacking between parallel benzene rings of adjacent 4-hy­droxy-3-meth­oxy­benzaldehyde mol­ecules 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 mol­ecule of crystallization is also disordered over two positions in an occupancy ratio of 0.68 (5):0.32 (5).
