We present here the first crystalline assembly of a supramolecular structure formed by iron(III) 5,10,15,20-tetrakismesitylporphyrin via hydrogen bonding with charge compensating hydrosulfate residues. Two additional molecules of sulfuric acid provide hydrogen bonding connection of four iron porphyrin units to form a fragment with interporphyrin void where two iron sites are situated at 9.52 Å distance. The insertion of two molecules of sulfuric acid into cavity formed by four Fe(III) porphyrin molecules led to the formation of the cluster structure with dihedral angle of 53.3° between adjacent porphyrin molecules Fe(1A)N4/Fe(2A)N4 and parallel Fe(1A)N4/Fe(1B)N4 and Fe(2A)N4/Fe(2B)N4 planes. Such a supramolecular material, where four iron sites in the porphyrin ligand environment are strongly connected via network of the hydrogen bonds provides a new tool for exploring different applications involving multielectronic processes.
