Mol-ecules of the title compound, porphyrin-54,10 4,154,204-tetra-benzoic acid, C48H30N4O8, lie on sites of 2/m symmetry in the space group Cmca. The crystals consist of doubly inter-woven two-dimensional supra-molecular arrays sustained by multiple (COOH)2 cyclic dimeric hydrogen bonds, each mol-ecule of the porphyrintetra-benzoic acid coordinating to four neighbouring species. This structure, which encloses substantial spaces occupied by disordered dimethyl-formamide solvent mol-ecules, represents yet another supra-molecular isomer of this porphyrin.
