Bis(2,6-dihy­droxy­benzoato-κ(2) O (1) ,O (1′))(nitrato-κ(2) O,O′)bis­(1,10-phenanthroline-κ(2) N,N′)gadolinium(III)

In the mononuclear title complex, [Gd(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], the Gd 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–DHB [centroid–centroid distances = 3.5334 (18) and 3.8414 (16) Å] and phen–phen [face-to-face separation = 3.4307 (17) Å] ligands of adjacent complex molecules stabilize the crystal structure. Intra­molecular O—H⋯O hydrogen bonds are observed in the DHB ligands.
