摘　　要：The title inclusion complex with the formula [(C42H70O35)2 · (C6O2H6)3 · (H2O)21.2(CH3OH)2] has been crystallized and characterized by single crystal X-ray analysis. The complex crystallizes in the triclinic system, space group P1, with a =1.5500 (1), b =1.5536(1), c = 1.8246(1) nm, α = 113.17(2), β = 99.12(2), γ=103.37(3)? V = 3.7739(4) nm3, Z = 1; Dc =1.343 g/cm3, μ = 0.124 mm-1, F(000) = 1594, R = 0.0795 and S = 0.9639. Two independent molecules of β-cyclodextrin (β-CD) form a 'head-to-head' dimer. The fairly important factor of the position and stability of the guest in the host cavity is the solvation of the polar group of the guest. 关键词：SUPRAMOLECULAR CHEMISTRY CYCLODEXTRIN HYDROQUINONE CRYSTAL structure.
