摘要：

A new crystal of（E）-2-（2,4-dichlorophenoxy）-1-（5,5-dimethyl-2-oxido-1,3,2-dioxaphosphinan-2-yl）vinyl 2-（2,4-dichlorophenoxy）acetate has been determined by single-crystal X-ray diffraction. The compound crystallizes in triclinic, space group P1 with a = 7.9393（17）, b = 11.974（3） ?, c = 13.532（3） ?, α = 90.937（4）, β = 101.998（3）, γ = 101.363（4）°, V = 1231.5（5） ?3, Dc = 1.500 Mg/m3, Z = 2, F（000） = 568 and μ = 0.585 mm-1. The molecular packing in the crystal is the result of C（10）–H（10）···O（5） hydrogen bond, as well as weak π-π stacking interactions. The herbicidal activity results indicated that the title compound 3 showed 80～100% inhibitory activities against all of the tested weeds at a dosage of 150 g×ai/ha.
