Complexation of lead(II) by nicotinamide (nia): Crystal structure of polymeric Pb(nia)(NO3)2

Lead(II) nitrate complex with nicotinamide has been synthesized and characterized by elemental analysis, IR, 1H NMR, 13C NMR, UV–Vis spectroscopy and X-ray crystallography. The Pb2+ centres linked through nicotinamide and nitrate(V) ligands form a two-dimensional polymeric structure defining a double layer and each layer is also stabilized by hydrogen bonds of N–H⋯O and C–H⋯O type.
