Modulation of coordination in pincer-type isonicotinohydrazone Schiff base ligands by proton transfer

We present here two different coordination polyhedra of pincer type N2O hydrazone based ligands supplemented with thiocyanate ions. The compounds namely [Hg(SCN)2(HL1)] (1) and [Hg(SCN)2(HL2)] (2) hav

Synthesis, DNA binding properties and antibacterial activity of lanthanide complexes with 2-benzoylpyridine isonicotinoylhydrazone

Lanthanide(III) complexes of general formula [Ln(BPINH)2(NO3)](NO3)2 (where, Ln = La, Ce, Pr, Nd, Sm, and BPINH = 2-benzoylpyridine isonicotinoylhydrazone) have been synthesized under mild reaction conditions wi

Oxidovanadium(iv) and dioxidovanadium(v) complexes of hydrazones of 2-benzoylpyridine and their catalytic applications

Reactions between the tridentate ONN donor ligands, Hbzpy-tch (I) and Hbzpy-inh (II), with [VIVO(acac)2] in dry methanol give two different types of complexes, [VIVO(acac)(bzpy-tch)] (1) and [VIVO(OMe)(bzpy-inh)] (2), respectively. Irrespective of their nature in methanol upon aerial oxidation and precipitation both yield dinuclear [{VVO(bzpy-tch)}2(μ-O)2] (3) and [{VVO(bzpy-inh)}2(μ-O)2] (4). Treatment of 1 or 2 in methanol with H2O2 yields the oxidomonoperoxidovanadium(v) complexes [{VVO(bzpy-tch)}2(μ-O2)2] (5) and [VVO(O2)(bzpy-inh)] (6). Reactions of 3 and 4 with imidazolomethylpolystyrene cross-linked with 5% divinylbenzene (PS-im) in DMF give the polymer-supported PS-im[VVO2(bzpy-inh)] (7) and PS-im[VVO2(bzpy-tch)] (8). The compounds are characterized by various spectroscopic techniques and compounds 7 and 8 were also analyzed by thermal, atomic force microscopy (AFM), field-emission scanning electron micrographs (FE-SEM) as well as energy dispersive X-ray (EDAX) studies. The molecular structures of 3-5 and of [VVO(O2)(bzpy-inh)(H2O)]·0.5MeOH (6a) were determined by single-crystal X-ray diffraction, confirming the μ-bis(O) and ONN binding mode in the dinuclear complexes 3 and 4, as well as the side-on coordination of the peroxido ligand in 5 and 6a. The polymer-grafted compounds 7 and 8 were used for the catalytic oxidation of isoeugenol using aqueous H2O2 as an oxidant. The intermediate peroxido species, expected to be involved during catalytic action, were also generated from solutions of 1-4 and studied by UV-Vis and 51V NMR. The catalytic activity of the several systems was tested and the polymer-supported versions showed higher conversions than their neat counterparts. The polymer-supported complexes allow for recyclable catalytic systems, thus providing additional advantages over their homogeneous counterparts in terms of increased catalyst lifetime and easier separation from the reaction mixture.

Thermal behaviour and spectroscopic studies of complexes of some divalent transitional metals with 2-benzoil-pyridil-izonicotinoylhydrazone

New complexes of 2-benzoyl-pyridil-isonicotinoylhydrazone (L) with Cu(II), Co(II), Ni(II) and Mn(II), having formula of type [ML2] SO 4?xH2O (M = Cu2+, Co2+, Ni 2+, x = 2 and M = Mn2+, x = 3), have been synthesised and characterised. All complexes were characterised on the basis of elemental 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, being coordinated through the azomethine nitrogen, the pyridine nitrogen and carbonylic oxygen. Heats of decomposition, ΔH, associated with the exothermal effects were also determined.
