## Abstract The molecules of the (pyrazinecarbonyl)hydrazones of the heterocyclic aldehydes RCHO with R = pyrrol-2-yl, furan-2-yl, thien-2-yl and pyridin-2-yl corresponding to compounds (**2:** X = NH), (**2:** X = O), (**2:** X = S)and **3**, respectively, are formally rather similar. Despite this
The capacity of sulfur to form intramolecular five-or six-membered SÁ Á ÁH-N hydrogen bonding in aromatic amides is assessed. The five-membered SÁ Á ÁH-N hydrogen bonding is observed in crystal structures of five compounds, whereas the six-membered SÁ Á ÁH-N hydrogen bonding is revealed in crystal s
