摘    要:The crystal structure of gessypol acetic acid (C_(30)H_(30)O_8-CH_3COOH) has been determinedby X-ray diffraction method. The crystals are triclinic with space group P1, unit cell dimen-sions: a=14.278(7)A, b=6.924(5)A, c=14.706(6)A, α=91.90(5)°, β=92.34(3)°, γ=98.71(5)°, Z=2. The structure has been solved by direct methods and refined by full-matrixleast-squares to a final conventional R=0.063 for observed reflexions. The crystal structureshows that the gossypol acetic acid is a complex which consists of one gossypol molecule andone acetic acid molecule through hydrogen bonding. However, there are no additional hydro-gen bonds between these complexes. The crystal structure is stabilized by Van der Waalsinteractions only.
