　　A new Schiff base compound NSBSH,formulated as C38H40N8O13S2 has been synthesized by condensation of 5-nitrosalicylaldehyde and 4-methylbenzenesulfonohydrazide,and has been structurally characterized by X-ray single crystal diffraction analysis,elemental analysis,and IR spectrum.It crystallizes in monoclinic system,space group P2/c,with a = 13.7992(16)(A),b = 7.1410(8)(A),c = 21.403(2)(A),β =95.5660(10)°,V = 2099.1(4)(A)3.X-ray analysis reveals that the existence of obvious π-π stacking interaction between two adjacent aromatic ring planes.The inter hydrogen bond interactions connect the adjacent Schiff base units into a dimer unit,and these moieties are further propagated into the two dimensional(2D)supramolecular network by intermolecular weak interactions.The title compound displays strong photo-luminescence in the liquid state,as well as the high thermal stability.The experiment also shows that it has a good antibacterial activity in vitro antibacterial activity against Sarcina.
