The crystal structures of two title Schiff base derivatives, CHNO·CHO () and CHNOS (), were determined at 110 and 100 K, respectively. In the crystal of compound , the ()-'-[(1-indol-3-yl)methyl-idene]isonicotinohydrazide and ethanol mol-ecules are linked by O-H⋯O, N-H⋯O and N-H⋯N hydrogen bonds, forming a tape structure running along the axis direction. The tapes are weakly linked a C-H⋯N inter-action. In the crystal of compound , ()--methyl-2-[1-(2-oxo-2-chromen-3-yl)ethyl-idene]hydrazinecarbo-thio-amide mol-ecules are linked N-H⋯O and C-H⋯O hydrogen bonds, forming a helical chain along the -axis direction. The chains are further linked into a layer expanding parallel to (102) through C-H⋯S inter-actions.
两种标题席夫碱衍生物CHNO·CHO（）和CHNOS（）的晶体结构分别在110 K和100 K下测定。在化合物的晶体中，（）-'-[(1-吲哚-3-基)亚甲基]异烟酰肼和乙醇分子通过O-H⋯O、N-H⋯O和N-H⋯N氢键相连，形成沿轴方向延伸的带状结构。这些带通过C-H⋯N相互作用微弱相连。在化合物的晶体中，（）--甲基-2-[1-(2-氧代-2-色烯-3-基)亚乙基]肼基硫代酰胺分子通过N-H⋯O和C-H⋯O氢键相连，形成沿轴方向的螺旋链。这些链通过C-H⋯S相互作用进一步连接成平行于(102)扩展的层。
