Complex [Pb(BzImH)2py(H2O)2(NO3)2] · (BzImH)2py · H2O has been synthesized and characterized by IR-spectrum and CHN-elemental analysis. The crystal structure of this compound consists of monomeric units of [Pb(BzImH)2py(H2O)2(NO3)2] · (BzImH)2py · H2O. Each lead atom is chelating by the nitrogens of (BzImH)2py ligand and the oxygen atoms of nitrate anions and also the oxygen atoms of two water molecules. The Pb atom has an nine-coordinate geometry and around lead atoms is hemidirected.
