| Popis: | The title mononuclear complex, [Eu(C7H5O3)2(NO3)(C12H8N2)2], is isostructural with those of other lanthanides. The Eu atom is in a pseudo-bicapped square-antiprismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and by six O atoms, four from two 2,6-dihydroxybenzoate (DHB) ligands and the other two from a nitrate anion. π–π stacking interactions 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. Intramolecular O—H...O hydrogen bonds are observed in the DHB ligands. |
