Bis(2,6-dihy-droxy-benzoato-κO,O)(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')samarium(III).

ABSTRACT: The title mononuclear complex, [Sm(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], is isostructural with that of other lanthanides. The Sm atom is in a pseudo-bicapped square-anti-prismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and by six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from a nitrate anion. π-π stacking inter-actions between phen and DHB ligands [centroid-centroid distance = 3.528 (4) and 3.812 (3) Å], and phen and phen ligands [face-to-face separation = 3.420 (10) Å] of adjacent complexes stabilize the crystal structure. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.
