Abstract A new series of cadmium(II) and zinc(II) coordination polymers, formulated as [Cd1.5(μ-L)(μ-CH3COO)(μ-N3)(CH3OH)]·3CH3OH}n (1), [Zn(μ-L)Br]·CH3OH}n (2), [Zn(μ-L)I]·CH3OH}n (3), [Zn(μ-L)(N3)]·C2H5OH}n (4), and [Zn2(μ-L)2(μ-N3)2]n (5), was self-assembled from the metal(II) acetates (or nitrates), a multifunctional pyridine-hydrazone building block HL = 2-benzoylpyridine-isonicotinoylhydrazone}

Treatment of lead(II) acetate, Pb(CH3COO)2·3H2O, with an isonicotinoylhydrazone building block (HL) and in the presence of two different salts (NaN3 or NaClO4) as a source of auxiliary ligand, resulted in two novel coordination compounds, namely a discrete 0D complex [Pb4(μ3-L)(L)(μ-N3)(N3)][Pb(L)(N3)(MeOH)]·0.75MeOH (1) and a 2D coordinationpolymer [Pb(μ-L)(μ-CH3COO)Na(μ-ClO4)(MeOH)]n (2), respectively
analyses, IR spectroscopy, UV–VIS–NIR, EPR, as well as thermal analysis and determination of molar conductivity and magnetic moments. The thermal behaviour of complexes was studied using thermogravimetry (TG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC). The structure of L hydrazone was established by X-ray study on single crystal. The ligand works as tridentate NNO
