چکیده
|
A new 1,2,3-thiadiazole compound was synthesized and characterized by 1h nmr,ms and hrms. the crystal structure of the title compound (c12h11cln2o4s2,mr = 346.80) has been determined by single-crystal x-ray diffraction. the crystal is of triclinic,space group p-1 with a = 8.4425(17) å,b = 8.9801(18) å,c = 9.859(2) å,α = 84.36(3) °,β = 86.71(3)°,γ = 83.25(3)°,v = 737.9(3)å3,z = 2,f(000) = 356,dc = 1.561 g/cm3,μ = 0.557 mm-1,the final r1 = 0.0380 and wr2 = 0.0982 for 2160 observed reflections with i > 2σ(i). a total of 12585 reflections were collected,of which 2601 were independent (rint = 0.0364). the herbicidal activity of title compound was determined,the results showed the title compound displayed excellent herbicidal activity against brassica campestris.
