摘要：

Two polymorphs of the inclusion compound [(n-C4H9)4N]+·(C13H9O3)-·H2O havebeen prepared and characterized by X-ray crystallography. Polymorph 1: triclinic P 1 , a =13.4982(2), b = 13.5743(2), c = 17.1996(2) , α = 67.045(1), β = 77.845(1), γ = 88.762(1)°, V =2830.43(7)3, Z = 4, R = 0.0491, wR = 0.1276; Polymorph 2: tetragonal P43, a = b = 13.53690(1) , c = 30.8491(8) , V = 5653.02(16)3, Z = 8, R = 0.0448, wR = 0.0984. In these two crystalstructures, the hydrogen-bonded ribbons built of 4,4 -dihydroxybenzophenone (DHBP, C13H10O3)anions and water molecules are orderly arranged to generate two-dimensional host layers, withtetrabutylammonium cations contained between the layers to form the sandwich-like inclusioncompounds. The structures of 1 and 2, which exist as two polymorphs, both display the similarpacking pattern and hydrogen-bond linking model.
