摘要：The title compound 5,7-dimethoxy-(2,4-dichlorophenoxyacetylimino)-2H-l,2,4-thiadiazolo[2,3-α]pyrimidine has been synthesized. In order to investigate the relationship between the structure and herbicidal activity of the target compound, we report its crystal structure and herbicidal behavior in the present paper. Crystallographic data: C15H12N4O4Cl25, Mr = 415.25, monoclinic, space group P2 1/n, α = 10.7361 (8), b = 11.9610(9), c = 13.0990(10) A, β = 96.988(2)°, Z = 4,V = 1669.6(2) .A^3, Dc = 1.652 g/cm^3, F(000) = 848, R = 0.0394, wR = 0.0797 and μ(MoKα) = 0.545 mm^-1。
