摘　　要：The crystal and molecular structures of the title compound (C15H14N2O5S, Mr = 334.34) were determined by X-ray diffraction. The crystal structure is of triclinic, space group P with a = 7.306(1), b = 7.933(1), c =14.146(2) ?, a = 81.95, b = 80.28, g = 72.92? V = 768.9(2) 3, Z = 2, Dc = 1.444 g/cm3 , = 0.238mm-1, F(000) = 348, S = 1.033, the final R = 0.0453 and wR = 0.1181 for 2704 observed reflections with I >2s(I). In the molecule there are three different planes. In each of them a conjugated system is formed. The intra-molecular hydrogen bond between N and H atoms was ascertained and a five-membered ring including hydrogen bond is formed.The crystal and molecular structures of the title compound (C15H14N2O5S, Mr = 334.34) were determined by X-ray diffraction.
