Its structure was characterized by IR, 1H-NMR, 13C-NMR, EA and single-crystal X-ray diffraction. The crystal of the title compound belongs to the monoclinic system, space group P2dc with a = 8.8437(18), b = 16.128(3), c = 12.305(3) A, β = 91.68(3)°, V= 1754.4(6) A3, Z = 4, Dc = 1.671 g/cm3,μ(MoKa) = 0,71073 mm^-1, F(000) = 888, R = 0.0384 and wR = 0.0778. Weak π-π interactions occur between the isothiazole rings and phenyl rings of adjacent molecules to form a one-dimensional chain and stabilize the crystal structure. Bioassay indicates that the title compound has good activity against the fungi and TMV tested.展开更多
