Figure 1.7
The Ebind values for C6H5X–C6H6 pff dimers (a) can be approximated very well as the Ebind values for HX–C3H6 complexes (b) where the X substituents in C6H5X and HX are the same. This supports the hypothesis that arene–arene interactions are best understood as local, through-space, interactions between proximal regions of the adjacent aromatics.55
