Abstract: In the title compound, [Pb(NO₃)₂(C₁₃H₈N₄)₂], the Pb^II atom (site symmetry 2) is hexacoordinated 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, intermolecular bifurcated N-H(O,O) hydrogen bonds connect the molecules into chains propagating along [100]. Adjacent chains interact by strong aromatic - stacking interactions, with a centroid-centroid distance of 3.483 (2) Å.
