The title mononuclear complex, [Eu(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], is isostructural with those of other lanthanides. The Eu atom is in a pseudo-bicapped square-anti-prismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and by six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from a nitrate anion. π-π stacking inter-actions between phen and DHB ligands [centroid-centroid distances = 3.5312 (19) and 3.8347 (16) Å], and between phen and phen ligands [face-to-face separation = 3.433 (4) Å] of adjacent complexes stabilize the crystal structure. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.
