2-(4-Decarboxydehydroabietyl)-5-p-toyl-[1,3,4]-oxadiazole, C28H34N2O, has been synthesized and characterized by IR, NMR, elemental analysis and single-crystal X-ray diffraction method. The crystal belongs to the orthorhombic system, space group P212121 with a = 6.1351(5), b = 14.8495(19), c = 25.9050(2) A, V = 2360.0(4) A3, Z = 4, Mr = 414.57, Dc = 1.167 Mg/m^3, 2 = 0.71073 A,μ(MoKa) = 0.070 mm^-1, F(000) = 896, the final R = 0.0452 and wR = 0.1076 for 1647 observed reflections with I 〉 2σ(I). There are five rings in the crystal structure of the title compound, but the oxadiazole ring is non-coplanar with the benzene ring D. 相似文献
