Abstract

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-anti-prismatic geometry formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, four O atoms from two 2,6-dihy-droxy-benzoate (DHB) ligands and two O atoms from a nitrate anion. Inter-molecular π-π stacking inter-actions 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. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.
