摘要
A new inclusion complex thiourea with tetrabutylammonium salicylate and water, 4(C4H9)4N+C7H5O3 ?4(NH2)2CS?2H2O, has been prepared and characterized by X-ray crystallo- graphy. Crystal data: MoKα radiation, triclinic, space group P1 with a = 13.505(5), b = 13.645(5), c = 30.720(10) ?, α = 92.872(7), β = 92.329(7), γ = 92.538(7)°, V = 5643.0(3) ?3, C96H184N12O14S4, Mr = 1858.79, Z = 2, Dc = 1.094 g/cm3, μ = 0.143 mm-1, F(000) = 2040, R = 0.0694 and wR = 0.1282 for 4303 observed reflections with I > 2σ(I). There are three different layer type host-lattices in the crystal structure of the title compound. All of them are formed by [(NH2)2CS·(C7H5O3 )]4 tetramers, but water molecules are located between tetramers and link them by hydrogen bonds to generate ribbons at c = 0 and 1/2, and isolated tetramers are arranged side by side at c = 1/4. The tetrabutylammonium cations are sandwiched between puckered layers.
