Chlorido-[5,10,15,20-tetra-kis-(quinoline-7-carboxamido)-porphinato]iron(III).

The title compound, [Fe(C(84)H(52)N(12)O(4))Cl], crystallizes in space group C2/c. The central Fe(III) cation (site symmetry 2) is coordinated in a fivefold manner, with four pyrrole N atoms of the porphyrin core in the basal sites and one Cl atom (site symmetry 2) in the apical position, which completes a slightly distorted square-pyramidal environment. The porphyrin macrocycle shows a characteristic ruffled-shape distortion and the iron atom is displaced out of the porphyrin plane by 0.42†à with the average Fe-N distance being 2.054†(4)†à ; the Fe-Cl bond length is 2.2042†(7)†à . Inter-molecular C-H⋯N and C-H⋯O hydrogen bonds occur in the crystal structure.
