Abstract

The clathrate of gossypol with tropolone is prepared for the first time and studied by X-ray diffraction. The structure is determined and refined using 7307 reflections (Siemens SMART/CCD diffractometer). The crystals are monoclinic, C30H30O8 · 2C7H6O2, a = 35.5892(1) Å, b = 12.8893(2) Å, c = 18.5910(2) Å, β = 118.54(3)°, Z = 8, space group C2/c, and R = 0.058. Each gossypol molecule is linked to two tropolone molecules through hydrogen bonds. The host (gossypol) and guest (tropolone) molecules form separate bilayers that are parallel to the bc plane and alternate along the a-axis.
