In the present work, we synthesized Ethyl-4-{[}N,N-bis (p-toluene sulfonyl)amino]benzoate crystal and structurally characterized by X-ray diffraction (XRD) method. The optimized geometry and vibration wave numbers of the compound investigated was obtained by performing density functional theory (DFT) computations at the M06-2X level of theory and with the 6-311+G(d,p) basis set. The DFT findings show good agreement with the experimental XRD data. Natural bond orbital (NBO) study was performed at the M06-2X/6-311+G(d,p) level to find the stability due to charge delocalization and hyperconjugative interactions. Charge transfer properties and chemical activities at different sites of the synthesized compound was quantitatively determined by performing frontier molecular orbital (FMO) analysis and molecular electrostatic potential (MEP) surfaces at the M06-2X level of theory with 6-311+G(d,p) basis set. The global reactivity parameters were explored with use of the energy of the FMOs. These descriptors predicted the stability of the investigated molecule by revealing the larger hardness and less softness values. Nonlinear optical (NLO) properties was computed at the M06-2X level of theory and 6-311+G(d,p) basis set combination which is observed larger as compared to the urea molecule indicating the considerable NLO character.
