英文摘要：

A new inclusion complex, （C4H9）4N^＋.12C4H2O42-.12C4H4O4.3（NH2）2CS, is prepared and characterized by X-ray crystallography. Crystal data： triclinic, space group P 1（No. 2）, a=0. 946 20（13） nm, b 1. 184 28（16） nm, c=1. 670 3（2） nm, α=93. 742（2）°,β=91. 171（2）°, γ=109. 783（2）°, Z=2, V：1. 755 7 （4） nm^3, Dc=1. 108 g·cm^-3, μ（MoKα）：0. 071 mm ^-1, F（000） =636 and R1 =0. 091 0 for 6 113 independent reflections. In the crystal structure of the title compound, a pair of opposite walls of the rectangle channel-like lattice are built of a parallel arrangement of puckered thiourea layers that are interlinked by three independent thiourea molecules through N-H…S hydrogen bonds and extended to a （001） family of plane. Another pair of walls is formed by dimers of fumarate molecule and fumarate anion. The tetra-n-butylammonium cations are stacked to give two columns within each channel with cross-sectional size of about 0. 946 × 0. 138 8 nm^2.
