Crystal structure of 2-{[2-methoxy-5-(trifluoromethyl)phenyl]iminomethyl}-4-nitrophenol
Karadayi, Nevzat; Sahin, Songul; Koysal, Yavuz; Coskun, Emine; Büyükgüngör, Orhan (Int Union Crystallography, 2015)In the title compound, C15H11F3N2O4, the N=C bond of the central imine group adopts an E conformation. The dihedral angle between two benzene rings is 6.2 (2)degrees. There is an intramolecular bifurcated O-H center dot ... -
DFT and TDDFT investigation of the Schiff base formed by tacrine and saccharin
Acar, Nursel; Selcuki, Cenk; Coskun, Emine (Springer, 2017)Schiff bases have many chemical and biological applications in medicine and pharmaceuticals due to the presence of an imine group (-C=N-). These bases are used in many different fields of technology, and in photochemistry ... -
Electrochemical and Spectral Studies of the Interaction of Niflumic Acid with Metavanadate (VO3-) Ions
Coskun, Emine; Bicer, Ender; Bulut, Iclal (Esg, 2015)The voltammetric behavior of niflumic acid (HNIF) in the presence and absence of vanadium (V) was investigated using square-wave (SW) voltammetry at physiological pH. SW voltammogram of HNIF exhibited only one cathodic ... -
