摘要

Derivatives hydrazone are attributed interesting pharmacological properties. The compound under study (E)-ethyl 4-(2-(thiofen-2-ylmethylene) hydrazinyl)benzoate (1), crystallized from ethanol as translucent light yellow thin plates. They are monoclinic, space group P2_1/c, with unit cell parameters a = 8.846(6), b = 20.734(14), c = 7.583(5) ?, β = 95.743(13), V = 1383.8(16) ?~3. Three hydrogen bonds and two intermolecular π-interaction perpendiculars to the hydrogen bonds patterns are observed in the crystal structure. A detailed description of these interactions will be presented. Also, semiempirical calculations (PM6) show the formation in the gas phase of a supramolecular chain, emulating the C(8) graph set seen in the crystal structure of the compound. Graphical Abstract: The synthesis and crystal structure of the title compound, C_(14)H _(14)N_2O_2S, is reported.[Figure not available: see fulltext.]
