While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)imino)methyl)phenol (2) crystalizes monoclinic P21/c space group. Both of the molecules which adopt (E) configuration with respect to the central C=N bond have strong intermolecular O―H∙∙∙N hydrogen bonds. These O―H∙∙∙N hydrogen bonds create S(6) motifs according to graph set notation. The optimized geometries of the molecules have been calculated by using Density Functional Theory (DFT) with the 6-31G(d,p) basis set. Molecular Electrostatic Potential (MEP) map and Frontier Molecular Orbitals have been made for the optimized geometries. In addition to these studies, the theoretical IR spectra of the compounds, the experimental IR spectra of which have been recorded at 4000-400 cm-1 interval, have also been calculated with same level theory. The experimental and theoretical results were compared to each other. UR - https://ijcce.ac.ir/article_35424.html L1 - https://ijcce.ac.ir/article_35424_c3303d085f5267092ebbf279f2c2a710.pdf ER -
