    New glyoxime derivatives and their transition metal complexes
    (PLEIADES PUBLISHING INC, 2007) Yildirim, B.; Oezcan, E.; Deveci, P.
    Two new vic-dioxime ligands and their complexes with Co+2, Ni+2, Cu+2, Cd+2, and Zn+2 ions were synthesized. Primer amines (3,4-methylenedioxaaniline and 4-methylbenzylamine) reacted with antichloroglyoxime to give 3,4-methylenedioxaphenylaminoglyoxime (H2L1) and N-(4-methylbenzyl)aminoglyoxime (H2L2) ligands. Structures of the ligands and their complexes are proposed based on elemental analyses, IR, UV-Vis, and H-1 NMR spectra, magnetic susceptibility measurements, and thermogravi metric analyses (TGA).

    Structural characterization and second-order nonlinear optical behavior of metal complexes of ferrocene derivative
    (MAIK NAUKA/INTERPERIODICA/SPRINGER, 2019) Deveci, P.; Taner, B.; Özcan, E.; Kılıç, Z.; Karakaya, M.; Karakas, A.
    In this manuscript, a ferrocene-linked vic-dioxime ligand (LH2) and its metal complexes [Ni(LH)(2), Cu(LH)(2), Co(LH)(2)(H2O)(2), Cd(LH)(H2O)(Cl), and Zn(LH)(H2O)(Cl)] are synthesized, and their structures are studied by spectral methods. Redox behavior of the compounds is studied by cyclic voltammetry (CV). For approaching microscopic second-order nonlinear optical (NLO) behavior of the synthesized ligand and its diamagnetic Cd(II), Zn(II), Ni(II) complexes, the electric dipole moment , static dipole polarizability , and first hyperpolarizability values are computed using ab-initio quantum chemical procedure [finite field (FF)]. The accumulated data indicate that the compounds exhibit non-zero quadratic hyperpolarizability tensor components, implying microscopic NLO phenomena. The HOMOs, LUMOs and the HOMOLUMO band gaps for first and second frontier orbitals of LH2 ligand and its Cd(II), Zn(II), Ni(II) complexes are evaluated by means of the Hartree-Fock (HF) method.

    Synthesis and characterization of new (E,E)-dioximes and their divalent metal complexes
    (MAIK NAUKA/INTERPERIODICA/SPRINGER, 2007) Deveci, P.; Oezcan, E.; Taner, B.
    Two new soluble vic-dioxime ligands, 4-isopropylanilineglyoxime ((LH2)-H-1) and 4-benzylpiperidineglyoxime ((LH2)-H-2) were prepared by reacting 4-isopropylaniline and 4-benzylpiperidine with anti-chloroolyoxime. Ten metal complexes were obtanied by reacting both ligands with Cu(II), Ni(II), Co(II), Zn(II), and Cd(II) cations. The ligands and their metal complexes were elucidated by elemental analysis, IR, UV-vis, H-1 NMR, and C-13 NMR and also magnetic moments of the complexes were determined.
