Two series of lanthanide compounds, namely, chlorides containing different numbers of both 1,10-phenanthroline (Phen) molecules and chloride anions in the first coordination sphere, and Schiff Bases (SBs) derived from Pyridoxal (PL) and amino acids, were characterized by single crystal X-ray diffraction and luminescence techniques. The combined use of these techniques for the analysis of long-distance europium non-covalent interactions was performed for the first time. As a result, the correlation between supramolecular organization and the features of the EuIII electronic transitions was found for the compounds of the first series. Strong non-covalent interactions between pyridoxal rings of SBs (the second series of compound) led to the formation of 1:2 species and four-dentate coordination function of these SBs in aqueous solution.
