Abstract
FT-IR and FT-Raman spectra of 2-Benzylsulfanyl-4-[(4-methylphenyl)-sulfanyl]-6-pentylpyrimidine-5-carbonitrile were recorded and analyzed. The structure of the molecule has been optimized and the structural characteristics have been determined by density functional theory. The geometrical parameters (DFT) are in agreement with the XRD results. HOMO and LUMO and other chemical properties are reported. Nonlinear optical properties are reported. A detailed molecular picture of the title compound and its interactions were obtained from NBO analysis. The negative (red and yellow) regions of the MEP are related to electrophilic reactivity and the positive (blue) regions to nucleophilic reactivity, as shown in the MEP plot and the title compound has several possible sites, C equivalent to N, N atom of pyrimidine ring and sulfur atoms for electrophilic attack. From the molecular docking studies it is clear that the title compound binds at the catalytic site of the substrate by weak non-covalent interactions most prominent of which are H-bonding, pi-pi, alkyl-pi, and amide-pi interactions.
