The title compound 2-(1-(3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carbonyl)piperidin-4-yl)-N-isopropylthiazole-4-carboxamide (C21H22BrClN6O2S, Mr=536.04) has been synthesized, and its structure was characterized by IR spectra, 1H-NMR, 13C-NMR, EA, and single-crystal X-ray diffraction. The crystal of the title compound belongs to monoclinic system, space group P/c with a=15.146(3), b=11.573(2), c=26.937(5) Å, β=103.64(3)°, V=1839.0(6) Å3, Z=4, Dc=1.557 g/cm3, μ(MoKa)=0.71073 mm-1, F(000)=2192, R=0.0601 and wR=0.1392. There exist one intramolecular hydrogen bond at N-H···N and four intermolecular weak interactions at O(2)···H(1), Cl(1)···H(12), O(1)···Cl(1) and S(1)···O(2). Bioassay results indicated that the title compound had good fungicidal and antiviral activities against tobacco mosaic virus.
