title: Bis(2,6-dihy-droxy-benzoato-κO,O)(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')praseodymium(III).
abstract: The mononuclear title complex, [Pr(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], is isostructural with related complexes of other lanthanides. The Pr(III) atom is in a pseudo-bicapped square-anti-prismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from nitrate anions. π-π stacking inter-actions 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. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.
