In the complex diaqua-tetra-nitrato[5-(pyridinium-4-yl)-10,15,20-tri-4- pyridylporphyrin]lanthanum(III) 1,2-dichloro-benzene tri-solvate, [La(NO 3)4(C40H27N8)(H 2O) 2]·3C6H4Cl2, the lan-thanum ion is coordinated to one of the peripheral pyridyl substituents of the porphyrin entity. Units of the complex are inter-linked to one another in three dimensions by a network of O - H⋯N, O - H⋯O and N - H⋯O hydrogen bonds between the water ligands, nitrate ions, and pyridyl and pyridinium groups of adjacent species. This is the first structural report of an exocyclic complex of the tetra-pyridylporphyrin ligand with any lanthanide ion and its self-assembly into a three-dimensional architecture sustained by hydrogen bonds.
