X-ray crystallography,2,5-bis(morpholino)-3,4-bis(p-chlorophenyl) thiophene,crystal structure
The title compound 2,5-bis(morpholino)-3,4-bis(p-chlorophenyl) thiophene 2 was obtained by the reaction of α-thio-p-chlorobenzoyl thioformmorpholine 1 with trimethyl phosphite in refluxing xylene. The crystal is of triclinic, space group P1- with unit cell constants: a =6.0740(1), b = 10.3250(1), c = 19.779(2) (A), α = 76.740(1), β = 87.110(1), γ = 74.920(1)°,C24H24C12N2O2S, Mr = 475.41, Z = 2, V= 1165.7(3) (A)3, Dc = 1.354 g/cm3, λ(MoKα) = 0.71073, μ =0.392 mm-1, F(000) = 496, the final R = 0.0324 and wR = 0.0819 for 3102 observed reflections (Ⅰ＞2σ(Ⅰ)). X-ray analysis reveals that the two morpholinyl groups are located at the α-position of thiophene, and the two p-chlorophenyl groups at the β-position. Therefore, the title compound is a new symmetricthiophene derivative.
