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

In the mononuclear title complex, [Dy(C(7)H(5)O(4))(2)(NO(3))(C(12)H(8)N(2))(2)], the Dy(III) atom is in a distorted bicapped square-anti­prismatic geometry formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, four O atoms from two 2,6-dihy­droxy­benzoate (DHB) ligands and two O atoms from a nitrate anion. Inter­molecular π–π stacking inter­actions between the phen and DHB ligands [centroid–centroid distances = 3.542 (4) and 3.879 (4) Å] and between the pyridine and benzene rings of adjacent phen ligands [centroid–centroid distance = 3.751 (4) Å] stabilize the crystal structure. Intra­molecular O–H⋯O hydrogen bonds are observed in the DHB ligands.
