We report the synthesis and characterization of a symmetric [N4] tetradentate imine-type ligand H2L that incorporates a dansyl fluorophore group in both ligand arms. Two binding domains separated by a short arene spacer and two bulky arms with an anti conformation make this organic molecule suitable as precursor of metallosupramolecular species such as helicates. The molecular structure of H2L has been analyzed by X-ray diffraction. This technique has revealed the formation of intermolecular hydrogen bond interactions that lead to the supramolecular self-assembly of ligand molecules in the solid state and the generation of oval-shaped channels in the 3D crystal packing.
