摘要：
The title compound N-(2-ethoxyphenyl)-3-oxobenzo[d]isothiazole-2(3H)-carboxa-mide(C16H14N2O3S,Mr = 314.35) has been synthesized and structurally characterized by IR,1H NMR and single-crystal X-ray diffraction.The crystal belongs to triclinic,space group P with a = 4.6395(15),b = 8.689(3),c = 17.917(7),α = 87.763(9),β = 84.625(9),γ = 82.344(9)°,V = 712.4(4)3,Z = 2,Dc = 1.465 Mg·m-3,λ(MoKa) = 0.71073,F(000) = 328,μ(MoKa) = 0.242 mm-1,the final R = 0.038 and wR = 0.089.A total of 3702 unique reflections were collected,of which 2762 with I > 2σ(I) were observed.X-ray analysis revealed that the benzisothiazolone ring and benzene moieties were essentially planar,and three intramolecular hydrogen bonds N(2)-H(2N)…O(1),N(2)-H(2N)…O(3) and C(10)-H(10)…O(2) were observed.The preliminary biologi-cal test showed that the title compound had antifungal and antibacteria activities against Bacillus subtilis(CMCC63003),Aeromonas hydrophila(ATCC7966),Staphylococcus aureus(ATCC6538),Escherichia coli(JM103),Blastomyces albicans,Gloeosporium papaya P.Henn,Colletotrichum gloeosporioides Penz and Botryodiplodia theobromae.
