Multiform host lattices in the layer type inclusion compound of thiourea with tetrabutylammonium salilcylate and water

A new inclusion complex thiourea with tetrabutylammonium salicylate and water, 4(C4H9)(4)N(+)C(7)H(5)O(3)(-.)4(NH2)(2)CS(.)2H(2)O, has been prepared and characterized by X-ray crystallography. Crystal data: MoKalpha radiation, triclinic, space group P (1) over bar with a = 13.505(5), b = 13.645(5), c = 30.720(10) Angstrom, alpha = 92.872(7), beta = 92.329(7), gamma = 92.538(7)degrees, V = 5643.0(3) Angstrom(3), C96H184N12O14S4, M-r = 1858.79, Z = 2, D-c = 1.094 g/cm(3), mu = 0.143 mm(-1), F(000) = 2040, R = 0.0694 and wR = 0.1282 for 4303 observed reflections with I > 2sigma(I). There are three different layer type host-lattices in the crystal structure of the title compound. All of them are formed by [(NH2)(2)CS (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..
