Bis(imidazo[4,5-f][1,10]phenanthroline)dinitratolead(II)

Abstract

In the title compound, [Pb(NO3)2(C13H8N4)2], the PbII 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 π–π stacking interactions, with a centroid–centroid distance of 3.483 (2) Å.
