The quantum theoretical calculations for crystal structure were performed by density functional theory(DFT/B3LYP/6-311+G*). From the optimized structure, geometric parameters were obtained and experimental measurements were compared with the calculated data. Frontier molecular orbitals(FMOs), total density of states(DOS), molecular electrostatic potential(MEP), molecular properties, natural charges, NMR parameters and NBO analysis for the product were investigated by theoretical calculations.展开更多

The yellow crystals of the title ylide were grown in methanol/chloroform solution by drop method without stirring at room temperature. The solid state structure of ylide has been established by X-ray crystallography analysis. In the molecule of the title compound, the geometry around the P atom is nearly tetrahedral and the O atom is in synperiplanar orientation to the P atom. The nitrophenyl ring is twisted with respect to the plane of the carbonyl group through an angle of 36.6(1)°. The crystal (C26H20NO3P, Mr = 425.40) belongs to the monoclinic system, space group P21/n with a = 10.889(3), b = 14.467(3), e = 13.872(4)A, β = 103.08(3)°, V = 2128.6(10) A3, Z= 4, T= 100(2) K, R = 0.059 and wR = 0.163 for 3984 observed reflections with I〉 2σ(I).展开更多
