Drug design is an integrated and developing system that portends an era of a novel and safe tailored drugs. It involves studying the effects of biologically active synthetic, semi-synthetic, and natural compounds based on molecular interactions in terms of molecular structure with activated functional groups or its unique physicochemical properties involved. The title compound, N-(2-aminophenyl)-2-(4-bromophenoxy) acetamide (c), was synthesized in a good yield and characterized by different spectroscopic techniques (1H, 13CNMR, and LC-MS) and finally, the structure was confirmed by X-ray diffraction (XRD) studies. The XRD data confirms that the cryatal structure is orthorhombic with space group of Pca21. The intermolecular interactions (N–H … O and N–H … Cg) inside the molecule stabilizes the crystal structure. The existence of this intermolecular interactions are computed by the Hirshfeld surfaces (HS) and two-dimensional (2D) fingerprints plot analysis. In addition to this, Energy frame work analysis is performed to quantify the interaction energies between the molecular pairs in a crystal by incorporating new version of CrystalExplorer17 using the energy model of HF/3-21G. Also to calculate the HOMO and LUMO energies, DFT calculations were carried out.
