Synthesis, Crystal Structure, and Biological Activities of 2-Oxo-2-aryl-1-(1,2,4-triazol-1-yl)ethyl phenylcarbamodithioate

The two title compounds, 2-oxo-2-p-tolyl-1-（1,2,4-triazol-1-yl）ethyl phenylcarbamodithioate（compound 3a） and 2-oxo-2-p-biphenyl-1-（1,2,4-triazol-1-yl）ethyl phenylcarbamodithioate（compound 3b）, were synthesized and {identified} by IR, EA and {}1H NMR spectra. The crystal structure of compound 3b was determined by X-ray diffraction analysis. The compound crystallized in a monoclinic system of space group P21/c with Mr=398.47（C 23 H 18 N4OS）, a=0.8769（2） nm, b=1.1924（2） nm, c=2.0440（6） nm, β=109.66（3）°, V=2.0126（8） nm3, Z=4, Dc=1.315 g/cm3, F（000）=832, μ=0.183 mm -1 , final R1=0.0819. The biological test result shows that the two title compounds exhibit certain fungicidal activities.
