Abstract
Based on single crystal X-ray diffraction studies for 1-(4-nitrophenyl)-3,5-di-thiophen-2-yl-1H-pyrazole (2a), monoclinic crystal system with a space group of C2/c was determined, where a final residual value of R equals to 0.058. The synthesized compounds were characterized through 1H and 13C NMR spectroscopy, and its intermolecular interactions were considered utilizing 2D and 3D Hirshfeld surface studies. The optimized molecular geometry, vibrational frequencies, and frontier molecular orbital energies of the title molecule were explored using density functional theory. Molecular modeling study revealed feasible binding modes of the title compound to protein targets, which showed small binding free energies.
Graphical Abstract
