Inclusion complexes of the natural product gossypol. Recognition by gossypol of halogeno methanes. Structure of the dichloromethane complex of gossypol and single crystal conservation after decomposition

摘要: The structures of gossypol complexes are extremely sensitive to the halogenomethane present as guest; e.g. changing number Cl atoms in chloromethane derivatives changes structure complex. crystals C30H30O8·CH2Cl2 monoclinic, space groupC2/c,a=21.320(4),b=19.199(6),c=15.765(2)A, β=113.05(2)o,V=5916(2)A3,Z=8,D x=1.35 g/cm3,T=295 K. has been solved by direct methods and refined finalR value 0.084 for 1828 reflections. In H-bonded molecules form columns, generating channels which filled guest molecules. After decomposition (desolvation) monocrystals conserved without destruction, there rather wide empty though slightly smaller than An attempt is made explain some peculiarities behavior polymorph formed on basis its with channels.
