Abstract: Dihydrogen-bonded complexes formed from pyrrole and a series of small molecules were studied at density functional B3LYP/6-311++G(d, p) level of theory. The topological characters of the electron density and atomic integral characters of the dihydrogen-bonded complexes were investigated extensively. Especially, the changes of atomic net charge, dipole moment, energy and volume of both the proton-donors and acceptors in the forming process of dihydrogen-bond were discussed.

Key words: Dihydrogen bond, Electron density, Topological analysis, Pyrrole, Atomic integral character
