چکیده مقاله:
Abstract: We present a detailed DFT study on structure, interaction energy and nature of bifurcated chalcogen bonds formed between XCY molecule (X = O, S; Y = S, Se and Te) and 1,2-dihydroxybenzene or 1,2-dimethoxybenzene. The interaction energies for these complexes are in the range of -1.96 to -6.91 kcal/mol. To better understand the nature of bifurcated chalcogen bonds, molecular electrostatic potential and quantum theory of atoms in molecules analyses are performed. Noncovalent interactions play a vital role in various fields of chemistry and biochemistry. They are responsible for the stability and structure of biomacromolecules, such as DNA and proteins.
