Weak interactions in metallo-supramolecular grid crystals: an analysis of their effects

The technique of Hirshfeld surface analysis has been applied to a selection of crystal structures of metallo-supramolecular grids in order to better define the modes of interaction of the grids with both anionic and neutral species, and to assess the possibilities of using grids as selective receptors. The influence of weak interactions on grid symmetry and hence inequivalence of metal sites within the grids has also been considered as a factor influencing possible electronic uses of grid species.
