Although 3-indolepropionic acid and phenanthridine are achiral molecules, a chiral bimolecular crystal is spontaneously formed; torsional conformation of the propionic acid group plays an important role in the helix formation through hydrogen bonding chain within the crystal lattice.
## Abstract The stability constants of the complexes formed by the polyfunctional macroβcyclic receptor molecules of type **1** with cationic substrates have been determined and analyzed in terms of structural factors. The binding strength is dominated by electrostatic interactions; the tetracarbox
