2-Chloro-N-{2-fluoro-5-[N-(phenylsulfonyl) phenylsulfonamido]phenyl}benzamide was synthesized and its crystal structure was also determined by X-ray single-crystal diffraction. The title compound(C25H18CIFN2O5S2) belongs to monoclinic, space group P21/n with a=0.7377(3) nm, b=1.2036(5) nm, c=2.6846(11) nm, β-90.895(9)°, V=2.3833(16) nm3, Mr=544.98, Z=4, Dc=1.519 g/cm3, μ=0.385 mm−1, F(000)=1120, R1=0.0632, and wR2=0.1438. Its crystal structure belongs to a novel class that has not been reported yet, and its preliminary herbicidal activity was also tested. Its inhibition rate to seedling growth of barnyard grass reaches 15.1% at 100 μg/mL.
