dc.description.abstractThe crystal structures of two title Schiff base derivatives, C15H12N4O·C2H6O (1·EtOH) and C13H13N3O2S (2), were determined at 110 and 100K, 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.
