Abstract: The title compound, [Eu(C₁₂H_9.33N₂O)₃]NO₃, was obtained by the reaction of Eu(NO₃)·3H₂O and the Schiff base ligand 2-(2-pyridyliminomethyl)phenol. The Eu atom is located on a threefold rotation axis and is nine-coordinated by three tridentate Schiff base ligands in a distorted tricapped trigonal-prismatic geometry. The O atom at the phenol hydroxy group is partially deprotonated and the H atoms are modelled with one-third occupancy according to the space group R. Offset face-to-face - [centroid-centroid distance = 3.886 (3) Å] and edge-to-face C-H interactions are found between adjacent molecules. An intramolecular O-HN hydrogen bond is also present.
