X-ray structural investigation of gossypol and its derivatives. VII. Molecular and crystal structure of dianilinegossypol

A complete x-ray structural investigation of the complex of dianilinegossypol with ethyl acetate has been made and it has been shown that in these crystals the dianilinegossypol gossypol has predominantly the quinoid tautomeric form.A.
