    Hydrothermal synthesis and characterization of two dimensional coordination polymers with 2,2′-dimethylglutarate and 1,2-bis(imidazol-1-ylmethyl)benzene
    (Elsevier, 2019-03-24) Yaman, P. K.; Erer, H.; Arici, M.; Fındıkçı, İlknur Eruçar; Yesilel, O. Z.; Mechanical Engineering; FINDIKÇI, Ilknur Eruçar
    The hydrothermal reactions of some metal ions with 2,2'-dimethylglutaric acid (22dmgH(2)) and 1,2-bis(imidazol-1-ylmethyl)benzene (obix) newly afford four coordination polymers are called, {[Co-2 (mu-22dmg)(2)(mu-obix)(2)]center dot 1.5H(2)O}(n) (1), {[Cu(mu-22dmg)(mu-obix)]center dot H2O}(n) (2), {[Zn-2(mu-22dmg)(2)(mu-obix)(2)]center dot 2H(2)O}(n) (3) and [Cd-2(mu-22dmg)(2)(mu-obix)(2)(H2O)](n) (4). All of the complexes were characterized by elemental analysis, IR spectra, single crystal X- ray diffraction, powder X-ray diffraction (PXRD), and thermal analysis techniques. Furthermore, photoluminescence and topological properties were studied. The X-ray single crystal study shows that complexes 1, 3 and 4 display 3-fold parallel interpenetrating networks with hcb topology showing an unusual 2D + 2D + 2D -> 2D structures. Topological analysis reveals that complex 2 has an uninodal 4-c net sql topology with the point symbol of 4(4).6(2). Atomically-detailed simulations were finally performed to compute hydrogen (H-2) uptake in these complexes at 77 K.

    Zinc(II) and cadmium(II) coordination polymers containing phenylenediacetate and 4,4′-azobis(pyridine) ligands: Syntheses, structures, dye adsorption properties and molecular dynamics simulations
    (Elsevier, 2017) Sezer, G. G.; Arıcı, M.; Fındıkçı, İlknur Eruçar; Yeşilel, O. Z.; Özel, H. U.; Gemici, B. T.; Erer, H.; Mechanical Engineering; FINDIKÇI, Ilknur Eruçar
    Two new coordination polymers (CPs) – [Zn(µ4-ppda)(µ-abpy)0.5]n(1) and [Cd(μ3-opda)(µ-abpy)0.5(H2O)]n(2) (o/ppda = 1,2/1,4-phenylenediacetate, abpy = 4,4′-azobis(pyridine)) – have been synthesized by using Zn(II)/Cd(II) salts in the presence of o- and p-phenylenediacetic acid and abpy under hydrothermal conditions. Their structures have been characterized by FT-IR spectroscopy, elemental analysis, X-ray powder diffraction and single crystal X-ray diffraction techniques. The structural diversities were observed depending on anionic ligands and metal centers in the synthesized complexes. Complex 1 consists of a 2-fold interpenetrated 3D+3D→3D framework with pcu topology while complex 2 has a 2D structure with sql topology. The adsorption of methylene blue (MB) was studied to examine the potential of the title CPs for removal of dyes from aqueous solution. Molecular dynamics (MD) simulations were also performed to examine diffusion of MB in 1 and 2. Thermal and optical properties of two complexes were also discussed.
