The title compound N-4-methyl-1,2,3-thiadiazole-5-carbonyl-N＇-3,5-dichloro-4- （1,1,2,2- tetrafluoroethoxyl）phenyl urea （C13H8Cl2F4N4O3S, Mr = 447.19） has been synthesized from 4-methyl- 1,2,3-thiadiazole-5-carbonyl chloride as the starting material, and its structure was characterized by proton Nuclear Magnetic Resonance （1H NMR）, Infra Red Spectroscopy （IR）, high-resolution mass spectroscopy （HRMS）, and single-crystal X-ray diffraction. The crystal of the title compound belongs to triclinic, space group Pi with a = 6.0780（8）, b = 11.3760（14）, c = 12.1440（18） A, α = 96.887（7）, β = 91.027（12）, γ= 104.252（13）°, Z = 2, V= 806.98（19）A3, Dc = 1.840 g/cm3, μ= 0.601 mm-1, F（000） = 448, R = 0.0450 and wR = 0.0869. X-ray analysis indicates that the 1,2,3-thiadiazole ring is not coplanar with the phenyl ring, and the dihedral angle is 33.57°. Two intermolecular hydrogen bonds N（2）-H…O（1 ）, S（1 ）…H-C（11）, and three weak intermolecular interactions, C（11）…O（1）, N（1）…O（2） and S…O（1）, are observed. The bioassay results indicate that the title compound has good insecticidal activity against Culex pipiens pallens and good induction activity for tobacco against tobacco mosaic virus which is equal to that of TDL.

The title compound N-（（1-cyclohexyl-lH-tetrazol-5-yl）（5-methyl-l,2,3-thiadia- zol-4-yl） methyl）-4-nitrobenzenamine （C17H20N8O2S, Mr = 400.47） was synthesized via Ugi four- components condensation reaction （U-4CR）, and its structure was characterized by IR, aH NMR, high-resolution mass spectrometry and single-crystal X-ray diffraction. The crystal belongs to orthorhombic, space group Pna21 with a = 20.390（2）, b = 12.9660（14）, c = 6.9399（8） A,β = 90.00°, Z = 4, V= 1834.7（3）A3, Mr = 400.47, Dc = 1.450 g/cm3, μ= 0.210 mm-1, F（000） = 840, R = 0.0348 and wR = 0.0717. X-ray analysis reveals that the dihedral angles formed between the thiadiazole and tetrazole rings, the benzene and tetrazole rings and the thiadiazole and benzene rings are 62.59, 86.73 and 70.07°, respectively. Three intermolecular hydrogen bonds N（1）-H（2）...N（6）, C（4）-H（4B）...O（2） and C（17）-H（17）...N（3） are observed. Bioassay shows that the title compound has antifungal and antivirus activities against tobacco mosaic virus.
