Abstract

The off-symmetrical structure of the toluene⋯SbCl₃ complex is a consequence of the off-centre location of σ-holes at the Sb atom. DFT-SAPT calculations have been used to determine the total interaction energies and their components. The characteristic features of the pnicogen bonding are due to the concert action of electrostatic and dispersion interactions.
