Özet

Two new salicylideneaniline (SA) derivative compounds (E)-2-(((4-chlorophenyl)imino)methyl)-5-(diethylamino)phenol, compound (I), and (E)-2-(((3-chlorophenyl)imino)methyl)-5-(diethylamino) phenol, compound (II), have been synthesized and characterized by single crystal X-ray diffraction, IR spectroscopy, H-1 NMR, C-13 NMR and theoretical methods. Both of the compounds which are Schiff base derivatives are isomer of each other. While the-compound (I) crystallizes in centrosymmetric monoclinic space group P 2(1)/c, the compound (II) crystallizes in orthorhombic space group P 2(1)2(1)2(1). The theoretical parameters of the molecules have been calculated by using Hartree-Fock (HF) and density functional theory (DFT/B3LYP) with 6-31G (d,p) basis set. These theoretical parameters have been compared with the experimental parameters obtained by XRD. The experimental geometries of the compounds have been superimposed with the theoretical geometries calculated by HF and DFT methods. Furthermore, the theoretical IR calculations, molecular electrostatic potential maps (MEP) and frontier molecular orbitals have been created for the compounds. (c) 2017 Elsevier B.V.
