X-ray structural investigation of gossypol and its derivatives XXIV. Structure of a clathrate of dianilinegossypol with 1,2-dichloroethane

The crystal structure of the 1:2 clathrate of dianilinegossypol with 1,2-dichloroethane, which is unstable under ordinary conditions, has been determined. In the clathrate there are two systems of mutually perpendicular channels in which two crystallographically different molecules of the guest are arranged. No intermolecular H bonds of the host-guest type are observed in the structure of the clathrate.A. S.
