Abstract
A series of fluoro- and hydroxy-substituted thiocarboxyhydrazones, 2-(3-fluorobenzylidene)-N-methylhydrazinecarbothioamide (1), 2-(2,3-difluorobenzylidene)-N-methylhydrazinecarbothioamide (2), and 2-(2-hydroxybenzylidene)-N-methylhydrazinecarbothioamide (3), are synthesized and characterized by elemental analysis, IR and UV-vis spectra, and single crystal X-ray diffraction. Structures of the three compounds are similar, but with a slight modification due to fluoro substituting groups. The crystal structures of the compounds are stabilized by hydrogen bonds and π⋯π interactions. The antimicrobial activity of the compounds shows that they are effective against some bacteria.
