• to fill the space. The relatively strong halogen bonds in 1&DIOFB_A partially account for its larger population occupancy than 1&DIOFB_B. In both modes, there is no solvent-accessible space between the dimerized resorcinarene salts. The halogen bond donors connect the two resorcinarene like a solid
