    Investigation of the Molecular Structure of (E)-2-Bromo-6-[(4-bromo-2-methylphenylimino)methyl]-4-chlorophenol
    (Pleiades Publishing Inc, 2020) Kastas, G.; Kastas, C. Albayrak; Ersanli, C. C.; Kirca, B. Kosar
    In this study, the molecular structure of (E)-2-bromo-6-[(4-bromo-2-methylphenylimino)methyl]-4-chlorophenol has been investigated using crystallographic (XRD), spectroscopic (UV-vis, NMR), and computational (DFT, HOMA) methods. The refinement parameters in XRD study supports the preference of phenol-imine form by the compound in solid state. The analysis of HOMA indices indicates that C1/C6 ring (tautomeric ring) deviates slightly from the aromaticity while the C8/C13 ring preserves its aromaticity in solid state. For the solvent-media dependence of the tautomerism, UV-vis and NMR spectra of the compound were investigated. It is found that the compound prefers only phenol-imine form in solvent media as in the case of solid state.

    Molecular Structure and Supramolecular Architecture of (E)-2-Bromo-6-[(2,4,6-Tribromophenylimino)methyl]-4-Chlorophenol
    (Pleiades Publishing Inc, 2020) Albayrak Kastas, C.; Kastas, G.; Kirca, B. Kosar; Ersanli, C. C.
    In this study, the molecular structure and supramolecular architecture of a new compound have been studied in depth using single crystal X-ray diffraction (XRD) technique. Crystallographic results show that the compound exists in phenol-imine form that is twisted with the dihedral angle of 51.77 degrees between the aromatic rings of the molecule. Various types of non-covalent interactions (C...O, C-H...O, Br...Br, C-H...Cl, pi...pi, O...Br, and Br...pi) take part effectively in the construction of 3D network in the compound. The C...O and C-H...O interactions have the role of forming the 1D structure along the direction [010] with the support of pi...pi and pi...Br interactions. The 2D structure of the compound is reached by the inter-connection of 1D chains in the (101) plane through the C-H...Cl interactions. The 3D supramolecular structure of the compound is completed by the non-covalent Br...Br and Br...O interactions responsible for the connection of 2D sheets.

    On the deformed Einstein equations and quantum black holes
    (Iop Publishing Ltd, 2016) Dil, E.; Kolay, E.; Ersanli, C. C.
    Recently q-deformed Einstein equations have been studied for extremal quantum black holes which have been proposed to obey deformed statistics by Strominger. In this study, we give the solutions of deformed Einstein equations by considering these equations for the charged black holes. Also we present the implications of the solutions, such as the deformation parameters lead the charged black holes to have a smaller mass than the classical Reissner-Nordstrom black holes. The reduction in mass of a classical black hole can be viewed as a transition from classical to quantum black hole regime.
