    The first example of calix[4]pyrrole functionalized vic-dioxime ligand: Synthesis, characterization, spectroscopic studies and redox properties of the mononuclear transition metal complexes
    (ELSEVIER SCIENCE SA, 2010) Taner, Bilge; Deveci, Pervin; Bereket, Soner; Solak, Ali Osman; Ozcan, Emine
    Novel calix[4] pyrrole bearing vic-dioxime ligand (LH2) of the general formula, R1R2C2N2O2H2 (where, R-1 = C6H5- and R-2 = C39H50N5-) has been synthesized by the reaction of anti-chlorophenylglyoxime with 3-aminophenylcalix[4] pyrrole at room temperature. The mononuclear Cu(II), Ni(II) and Co(II) complexes of this vic-dioxime ligand were prepared and their structures were confirmed by elemental analysis, FT-IR, TGA and magnetic susceptibility measurements; the HMBC, DEPT, H-1 and C-13 NMR spectra of the LH2 ligand were also reported. The electrochemical property of the complexes was investigated in DMSO by cyclic voltammetry at 200 mV s (1) scan rate. The cyclic voltammetric measurements clearly indicated that Co(LH)(2)center dot 2H(2)O complex differs from the Ni(LH)(2) and Cu(LH)(2) complexes upon the exhibition of quasi-reversible one-electron transfer reduction process in the negative region instead of an irreversible process.

    Synthesis, Characterization, Thermal and Redox Properties of a Vic-Dioxime and Its Metal Complexes
    (TAYLOR & FRANCIS LTD, 2010) Uçar, Asuman; Deveci, Pervin; Taner, Bilge; Fındık, Mükerrem; Bereket, Soner; Özcan, Emine; Solak, Ali Osman
    A new vic-dioxime ligand containing benzophenone hydrazone units, N'-(benzophenone hydrazone)glyoxime [LH2] has been prepared from benzophenone hydrazone and anti-chloroglyoxime in absolute ethanol. Mononuclear nickel(II), cobalt(II), copper(II), zinc(II), and cadmium(II) complexes were also synthesized. Ligand and complexes were characterized by elemental analyses, FT-IR, 1H NMR, and 13C NMR spectroscopy, magnetic moments, and DTA/TG techniques. On the basis of the magnetic and spectral evidences a square-planar geometry for Ni(II) and Cu(II) complexes, tetrahedral for Cd(II) and Zn(II) complexes, and octahedral for Co(II) complex were proposed. Redox behaviors of ligand and its complexes were also investigated by cyclic voltammetry at the glassy carbon electrode.
