    A Carboxylate-Bridged Mn(ii) Compound With 6-methylanthranilate/Bipy: Oxidation of Alcohols/Alkenes and Catalase-Like Activity
    (Taylor & Francis Ltd, 2018-05-04) Kilic, Yalcin; Bolat, Serkan; Kani, Ibrahim
    A novel manganese compound, [Mn-2((1,3)-6-CH3-2-NH2C6H4COO)(2)(bipy)(4)](ClO4)(2) (bipy=2,2-bipyridine), was synthesized and used as a catalyst precursor in the oxidation of alkenes and primary alcohols to corresponding aldehydes, ketones, and acids. The six-coordinate compound has a binuclear structure in which two Mn(II) ions adopt a syn-anti (1,3)-bridging mode with two carboxylate groups and two chelated bipy ligands. The compound exhibits good activity in the oxidation of cyclohexene to 2-cyclohexene-1-one as the major product (93% conv. in 3h, 79.3% selectivity) and of cinnamyl alcohol to cinnamaldehyde as the major product with 46% selectivity (100% conv. in 1.5h) with tert-butyl hydroperoxide (TBHP) in acetonitrile at 70 degrees C. Furthermore, the catalase-like activity of the compound was studied in different solvents (acetonitrile, methanol, Tris-HCl buffer; TOF=29,910h(-1) in Tris-HCl buffer).

    Synthesis and Characterization of Four Cu(II) Coordination Polymers Based on Glutarate and 3,3′-Dimethylglutarate Ligands
    (Elsevier, 2025-12) Demir, Sevde; Kilic, Yalcin; Coskun, Ferihan Tatas; Bicer, Figen Arslan; Yesilel, Okan Zafer; Tataş Coşkun, Ferihan; Arslan Biçer, Figen
    Four new Cu(II) coordination polymers, namely [Cu(mu -glu)(mim)(2)](n) (1), {[Cu(mu -glu)(emim)(2)]H2O}(n) (2), [Cu(mu (3)-dmg)(im)(2)](n) (3) and [Cu-4(mu (4)-dmg)(2)(pyz)](n) (4), where H(2)glu: glutaric acid, H(2)dmg: 3,3 '-dimethyl glutaric acid, im: imidazole, mim: 2-methyl imidazole, emim: 2-ethyl-4-methyl imidazole, pyz: pyrazine, have been successfully synthesized and structurally characterized by elemental analysis, IR and UV-Vis spectra, single crystal X-ray diffraction, powder X-ray diffraction (PXRD), and magnetic properties. X-ray diffraction studies have revealed that complexes 1 and 2 crystallize in the orthorhombic system, with space groups P2(1)2(1)2(1) (1) and Pbca (2), respectively, while compounds 3 and 4 crystallize in the monoclinic system, with space groups P2(1)/n (3) and C2/c (4), respectively. In compounds 1 and 2, the glu ligands adopt a bis(bidentate) bridging coordination mode, linking Cu(II) ions to form a one-dimensional linear chain. In compounds 3 and 4, the dmg ligands act as bridging linkers, adopting mu-eta(2):eta(0):eta(1):eta(0) and mu(4)-eta(1):eta(1):eta(1):eta(1) coordination modes, respectively, to construct 2D coordination polymer networks. Topological analysis results of complexes 3 and 4 show that complex 3 forms a 5-connected uninodal 2D framework with a Shubnikov plane net (3(3).4(3).5(4)) topology, while complex 4 forms a 6-connected uninodal 2D framework with a SP 2-periodic net (3(6).4(6).5(3)) topology. Moreover, thermal and optical absorption properties were studied. The thermal stability of the hydrated complexes follows order: 4 (200 degrees C) >3 (197 degrees C) > 1 (190 degrees C) > 2 (177 degrees C) in static air atmosphere. The optical absorption studies revealed that the calculated band gap values of complexes 1-4 are related to the type and structure of the ligands.

    Selective Catalytic Oxidation of Alkenes Employing Homobinuclear Manganese(ii) Catalysts With Tbhp
    (Pergamon-Elsevier Science Ltd, 2018-02) Kilic, Yalcin; Kani, Ibrahim
    The two novel homobinuclear compounds [Mn-2((II,II)) (mu(1,1)-4-CH3-C6H4COO)(2)(phen)(4)](ClO4)(2) (1) and [Mn-2((II,II)) (mu(1,3)-4-CH3-C6H4COO)(2)(bipy)(4)](ClO4)(2) (2), where bipy=2,2-bipyridine and phen=1,10-phenanthroline, have been synthesized and characterized by elemental analyses and spectral methods (UV-Vis, FTIR, and X-ray). A single-crystal X-ray diffraction structure analysis of the compounds revealed that the manganese atom is octahedrally coordinated. In compound 1, the binuclear(II) structure is monodentate, bridged with one oxygen atom of carboxylate ligand in mu(1,1) mode, and each Mn(II) center is coordinated with two phen ligands. In compound 2, the binuclear(II) structure is synanti bidentate, bridged with two oxygen atoms of carboxylate ligand in mu(1,3) mode, and each Mn(II) center is coordinated with two bipy ligands. The Mn-Mn separation is 3.441 (1)angstrom and 4.450 (1)angstrom for 1 and 2, respectively. The catalytic potentials of these compounds have been tested for the oxidation reaction of various olefins (i.e., styrene, cyclohexene, ethyl benzene, 1-hexene, 1-octene). The oxidation reactions were carried out in the presence of catalytic amounts of 1 and 2 with a peroxide oxygen donor (TBHP=tert-Butyl hydroperoxide) in acetonitrile at 70 degrees C. On comparing the catalytic activities of 1 and 2, both catalysts showed good activity (similar to 100% conv. in 24 h) in the oxidation of studied alkenes, and excellent conversion was obtained for cyclohexene (similar to 100% conv. in 3 h; TON = 265 and TON = 257, respectively, for 1 and 2).
