Özet

Hydrazones are an important class of organic compounds, which exhibit large pharmacological applications. Hydrazones have long been used for the synthesis of a wide range of useful heterocyclic compounds due to their reactivity toward electrophiles and nucleophiles. Herein, a hydrazone derivative, 2-[(2,3-dimethylphenyl)amino]-N'-[(E)-thiophen-2-ylmethylidene]benzohydrazide, noted C20H19N3OS was synthesized and its three-dimensional structure was determined by X-ray crystallography. Structural characterization by X-ray crystallography was supported by Density Functional Theory (DFT) calculations. Intermolecular interactions in the crystal network were determined using Hirshfeld surface analyses. The optimized geometry, global reactivity descriptors, Natural Bond Orbital (NBO) analysis, and HOMO-LUMO orbitals of the molecule were computed using the DFT-B3LYP method and 6-311++G (d,p) basis set. C20H19N3OS has a monoclinic system and P2(1)/c space group with parameters a = 13.9774 (13) angstrom, b = 16.3851 (16) angstrom, c = 8.2101 (8) angstrom, beta = 105.429 (7)degrees and Z = 4. C20H19N3OS forms an S (6) ring motif with an intramolecular N-H center dot center dot center dot O hydrogen bond. In the crystal, the molecule chains along the c-axis direction are linked by C-H center dot center dot center dot O hydrogen bond. Atomic charges were predicted using the Mulliken population and the NBO theory. The molecular electrostatic potential (MEP) picture was drawn using the same level of theory to visualize the chemical reactivity and charge distribution on the molecule. The local reactivity was examined by determining the Fukui functions and dual descriptor indices. (c) 2019 Elsevier B.V. All rights reserved.
