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.
