• Resumen

  • A series of hydrazone compounds, 4-methyl-N'-(4-nitrobenzylidene)benzohydrazide methanol solvate (1), N'-(4-hydroxy-3-nitrobenzylidene)-4-methylbenzohydrazide dimethanol solvate (2), and N'-(3,5-dibromobenzylidene)-4-methylbenzohydrazide (3), derived from 4-methylbenzohydrazide with different benzaldehydes, were synthesized and characterized by physico-chemical methods and single crystal X-ray diffraction. Crystals of the compounds are stabilized by intermolecular hydrogen bonds, as well as π···π stacking interactions. Antibacterial activity of the compounds against Staphylococcus aureus, Escherichia coli, and Klebsielle pneumoniae strains was studied. Compounds 1 and 2 have moderate minimum inhibition concentration values on the tested bacteria strains. Compound 3, with the Br-substituent groups, showed the highest activity on the bacterial strains.
