Crystal structures of the α- and β-phase inclusion complexes of dianilinegossypol with acetone obtained at 20° and 30 °C, respectively, have been determined by X-ray structure analysis. Crystal data of the α-phase complex are: C42H40O6N2⋅2C3H6O, orthorhombic, space group Pccn, a = 29.501(9), b = 10.866(2), c = 13.756(3) A, V = 4409(1) A3, Z = 4, Dx = 1.18 g cm-3. The structure has been refined to a final R value of 0.117 for 1401 observed reflections. The host–guest ratio for the β-phase complex is the same (1 : 2) and the crystals are monoclinic, space group C2/c, a = 28.352(6), b = 11.836(2), c = 13.196(1) A, β = 93.05(1)°, V = 4422(2) A3, Z = 4, Dx =1.18 g cm-3. The structure has been refined to a final R value of 0.077 for 1414 observed reflections.
