Abstract
Abstract
The title compound Ethyl 1-benzyl-2-(thiophen-3-yl)-1H-benzo[d]imidazole-5-carboxylate (BI) is prepared and characterized using spectroscopic methods. The theoretical optimization and three dimensional molecular structure are confirmed by X-ray diffraction method (single crystal). The C–H…π intermolecular interactions stabilize the crystal structure. The intermolecular contacts in the crystal structure are quantified using Hirshfeld surfaces and the crystal packing is elucidated using 3D energy frameworks analysis. In the frameworks, the dispersion energy term is dominated over the electrostatic energy term. The structural optimization was carried out with B3LYP/6-311++G (d, p) level of theory. The visual representations of positive and negative potentials (electrostatic potential) are mapped on the electron density isosurface. The band gap energy (HOMO-LUMO) of the molecule is calculated to be 4.36 eV. Structural conformation of BI is compared with similar structures.
