摘要：

3-(2-Hydroxy-phenyl)-5-phenyl-6-ethoxycarbonyl-cyclohex-2-enone was synthesized. Its composition and structure were characterized by elemental analysis, IR, UV, H-1 NMR and MS spectra, and the crystal structure was determined by X-ray single crystal diffraction method. The crystal of the compound belongs to monoclinic system with space group P2(1)/c, a = 1.41946(17) nm, b =0.58445(7) nm, c = 2.1756(3) nm, beta = 104.795(2)degrees, V= 1.7450(4) nm(3), Z = 4, D-c = 1.280 g . cm(-3), F(000) = 712, mu = 0.088 mm(-1), R-1[I > 2sigma(I)] = 0.0627, wR(2)[I > 2sigma (I)] = 0.1484. The crystal measurement showed that the cyclohexene unit of the title compound has a quasi-chair conformation, and a dimer with 16-membered cycle was produced by the intermolecular hydrogen bonding.
