A series of literature known (1–3) [1–4] and new Si-tripodal receptors for anion sensing, based on 1–3 pyridylmethyl functionalized side arms as recognition sites, was designed, successfully synthesized and characterized by ¹H and ¹³C NMR spectra (4–9). These ligands showed high selectivity and strong binding affinity toward investigated dicarboxyacid anions. The complexes formation was confirmed by ¹⁹F NMR spectra. All supramolecular complexes were structurally authenticated using parametric method 5 (PM5) with the MO-G for SCIGRESS program. The results brought information of the type and nature of intermolecular interactions present in the complexes and extended structures.
