Supramolecular Chemistry and Complexes

Hexachlorinated half-cage isomer acetates may be obtained from isodrin in acetic acid under the proper conditions and separated in highly pure form. The X-ray crystal structure of the “inside” acetate shows that it is still more sterically congested than the previously reported “outside” one. Bond lengths and angles for both isomers reveal large deviations from those normally found in saturated systems providing interesting models for the investigation of steric effects on chemical bonding.
