Notes:
The crystal and molecular structure of the complex formed by the ionized bistartro-[18]-crown-6 receptor molecule 1 with the ethylenediammonium cation, is described. The macrocycle is roughly planar, the carboxy groups of each tartaric acid residue being in a diaxial relationship and extending above and below this plane. This conformation allows ‘lateral’ interactions with bound species to occur.The substrate is sandwiched between two macrocycles, with one of its NH3+ heads anchored to the polyether core, and the other one in contact with the two carboxy groups of the neighboring molecule.
