A new Schiff base compound((NSBSH)2bipy·3H2O) based on 5-nitrosalicylal 4-methyl benzene-sulfonohydrazide(abbreviated as NSBSH), formulated as C38H40N8O13S2, has been synthesized by the condensation of 5-nitrosalicylaldehyde and 4-methylbenzenesulfonohydrazide, and 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), b = 7.1410(8), c = 21.403(2), β = 95.5660(10)o and V = 2099.1(4)3. X-ray analysis reveals that there are obvious π-π stacking interactions between two adjacent aromatic ring planes. The intermolecular hydrogen bonding interactions connect the adjacent Schiff base units into a binuclear unit, and further propagate these moieties into a two-dimensional(2D) supramolecular network. The title compound displays strong photoluminescence in the liquid state as well as high thermal stability. The experiment also shows that it has a good antibacterial activity in vitro antibacterial activity against Sarcina.
