biostudies-literatureUnknown65(Pt 1)Li CXIn the title compound, [Pb(NO(3))(2)(C(13)H(8)N(4))(2)], the Pb(II) atom (site symmetry 2) is hexa-coordinated by four N atoms from two N,N'-bidentate imidazo[4,5-f][1,10]phenanthroline (L) ligands and two O atoms from two weakly coordinated nitrate ions [Pb-O = 2.872 (5) Å] in an irregular arrangement, which may be ascribed to the stereochemically active lone pair of electrons on the metal ion. In the crystal, inter-molecular bifurcated N-H⋯(O,O) hydrogen bonds connect the mol-ecules into chains propagating along [100]. Adjacent chains inter-act by strong aromatic π-π stacking inter-actions, with a centroid-centroid distance of 3.483 (2) Å.Acta crystallographica.
