【 摘 要 】

A Schiff base compound, 4-hydroxy-benzaldehyd-thiosemicarbazide (C8H9N3OS), has been prepared by the reaction of 4-hydroxy-benzaldehyd with thiosemicarbazide in ethanol-water (v: V = 3:1) solution. The structure of 4-hydroxy-benzaldehyd-thiosemicarbazide was determined by single crystal X-ray diffraction. The result gives that the 4-hydroxy-benzaldehyd-thiosemicarbazide belongs to triclinic, space group P-1 with a = 4.0285(8) Å, b = 10.754(2) Å, c = 21.229(4) Å, α = 92.50(3)°, β = 90.11(3)°, γ = 99.36(3)°, V = 906.5(3) Å3, Z = 4, Dc = 1.431 mg•m-3, μ = 0.318 mm-1, F (000) = 408, and final R 1 = 0.1508, ωR 2 = 0.3641. The 4-hydroxy-benzaldehyd-thiosemicarbazide molecules form 1D chain structure by the O-H•S intermolecular hydrogen bond interaction.
