Its crystal structure was determined by X-ray diffractometry. The crystal belongs to the monoclinic system, space group P21 /c with a = 9.1628（7）, b = 12.9490（7）, c = 15.7898（11）, β = 103.952（8）o, Mr = 36.08, V = 1818.2（2）3, Z = 4, Dc = 1.382 g/cm3, F（000） = 788, μ = 0.179 mm-1, R = 0.0701 and wR = 0.1513. The preliminary biological test showed that the title compound has activities against Escherichia coli, S.albus, Bacillus subtilis, Staphylocc- ocusaureus and Micrococcus tetragenus with MIC to be 0.038, 0.038, 0.075, 2.48, and 0.15 mg/mL, respectively.展开更多
