Abstract
This study explores the supramolecular reactivity of the meso-tetra(3-pyridyl)porphyrin (T3PyP) building block in the context of crystal engineering. This ligand has coordination as well as hydrogen bonding tetradentate functionalities and exhibits orientational versatility of the 3-pyridyl substituents. Reactions of the T3PyP with copper and manganese chlorides afforded hybrid coordination polymers with uniquely interesting and novel architectures of three-dimensional connectivity, in which the metal ions have multiple oxidation states. Several different modes of intermolecular association have been observed in crystalline adducts of T3PyP with various aqua nitrate salts of lanthanoid metal ions, which bear multiple molecular recognition sites on their nitrate and water ligands. The porphyrin component in these structures is characterized by differently protonated states. It is either interlinked through the inorganic connectors into self-assembled three-dimensional architectures or exhibits self-complem...
