Abstract
The mononuclear title complex, [Pr(C7H5O3)2(NO3)(C12H8N2)2], is isostructural with related complexes of other lanthanides. The Pr(III) atom is in a pseudo-bicapped square-antiprismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and six O atoms, four from two 2,6-dihydroxybenzoate (DHB) ligands and the other two from nitrate anions. π–π stacking interactions between the phen and DHB ligands [centroid–centroid distances = 3.518 (2) and 3.778 (2) Å] and the phen and phen ligands [face-to-face separation = 3.427 (6) Å] of adjacent complexes stabilize the crystal structure. Intramolecular O—H⋯O hydrogen bonds are observed in the DHB ligands.
