The water-soluble cyclo-bisintercaland-type receptor molecules 3 a ± c, positively charged macrocyclic polyamines containing two large crescent-shaped quinacridine subunits, bind anionic aromatic substrates, such as nucleotides, by a combination of pstacking and electrostatic noncovalent interaction
## Abstract The crystal structures of four anion cryptates [X^−^ ⊂ **BT**‐6H^+^] formed by the protonated macrobicyclic receptor **BT**‐6H^+^ with F^−^, Cl^−^, Br^−^ and N have been determined. They provide a homogeneous series of anion coordination patterns with the same ligand. The small F^−^‐ion
