The crystal structure of an inclusion complex of benzyltrimethylammonium bromide with (R)-(+)-1,1′-binaphthalene-2,2′-diol has been determined by X-ray crystallography techniques. It is stabilized by strong and weak H-bonds, and crystallizes in the monoclinic space group P21 with unit-cell parameters of; a = 10.5345(10)Å, b = 9.90380(10)Å, c = 12.7437(10)Å, α = 90°, β = 104.1165(4)°, γ = 90°, V = 1289.42(2)Å3, and Z = 2. The benzyltrimethylammonium bromide molecule serves as space filler of the cage built by the rigid (R)-(+)-1,1′-binaphthalene-2,2′-diol molecules in an inclusion phenomenon.
