Abstract
The crystal structures of two title Schiff base derivatives, C15H12N4O·C2H6O (1·EtOH) and C13H13N3O2S (2), were determined at 110 and 100 K, respectively. In the crystal of compound 1·EtOH, the (E)-N′-[(1H-indol-3-yl)methylidene]isonicotinohydrazide and ethanol molecules are linked by O—H⋯O, N—H⋯O and N—H⋯N hydrogen bonds, forming a tape structure running along the b-axis direction. The tapes are weakly linked via a C—H⋯N interaction. In the crystal of compound 2, (E)-N-methyl-2-[1-(2-oxo-2H-chromen-3-yl)ethylidene]hydrazinecarbothioamide molecules are linked via N—H⋯O and C—H⋯O hydrogen bonds, forming a helical chain along the b-axis direction. The chains are further linked into a layer expanding parallel to (102) through C—H⋯S interactions.
