    Synthesis, crystal structure and spectroscopic studies of a new silver complex derived from [1-(3-pyridinyl) ethanone]
    (Elsevier, 2023) Celik, Sibel; Atilgan, Abdullah; Alp, Meryem; Yurdakul, Senay; Demircioglu, Zeynep; Ozdemir, Namik; Buyukgungor, Orhan
    In this work, a new silver (I) complex, [Ag(3-pye)2(H2O)](NO3) where 3-pye=1-(3-pyridinyl) ethanone, has been synthesized and characterized by elemental analyses, FT-IR, fluorescence spectroscopy, and single X-ray crystallography. The X-ray diffraction analysis revealed that the Ag(I) complex crystallized in the monoclinic system with the C2/c space group. Computational studies were performed using DFT approache on the present complex to get insight into the structural parameters, spectral characteristics and electronic properties. The characterization results were found to be consistent with the proposed structure of the complex, and the DFT approach supported the experimental results. Also, Hirshfeld surface analysis was used to identify the non-covalent interactions within the crystal structure as well as to visualize the conformity of the crystal structure.

    Synthesis, crystal structure, Hirshfeld surface analysis and molecular docking analysis of new cadmium(II) iodide complex with the pyridine, 4-(1,1-dimethylethyl)
    (Taylor & Francis Ltd, 2022) Celik, Sibel; Demircioglu, Zeynep; Yurdakul, Senay; Buyukgungor, Orhan
    This study was set out to introduce a newly synthesized cadmium complex, [Cd(4-tertbutyl-pyridine)(2)I-2], where t-BP = 4-tert-butyl pyridine. The complex was synthesized and characterized using elemental analysis, X-ray diffraction, FTIR, and photoluminescence combined with DFT calculations. The X-ray analysis of (Cd(t-BP)(2)I-2) revealed that the Cd center is approximately tetrahedrally coordinated with two nitrogen atoms from the 4-tertbutylpyridine groups and the two I ions forming an approximately tetrahedral geometry with tau(4) = 0.89. The presence of various intermolecular interactions and 2 D-fingerprint regions is supported by the Hirshfeld surface analysis. In the theoretical calculations, the density functional theory (DFT) method with the PBEPBE functional, the SDD basis set for Cd and I, and the 6-311 G(d) basis set for C, N, and H at the B3LYP/LANL2DZ level were chosen as the computational method. Systems based on electronic and optical properties were also discussed. The frontier molecular orbitals (FMO) analysis, chemical activity, local reactivity descriptors (Fukui functions), and NLO properties were examined for the compound at the LANL2DZ level of theory. The Cd(II) complex was studied by using molecular docking analysis to identify the active site and binding energies with anti-cancer receptors.
