The conformation about the central benzene ring in the mol-ecule of (I), CHNO, is partially determined by an intra-molecular N-H⋯O hydrogen bond. In the crystal, chains parallel to the axis are generated by inter-molecular N-H⋯O hydrogen bonds with the chains assembled into a three-dimensional network structure by inter-molecular C-H⋯O hydrogen bonds and C-H⋯π(ring) inter-actions. The mol-ecule of (II), CHNO, differs from (I) only in the substituent at the hydrazide N atom where a phenyl-methyl-ene moiety for (II) is present instead of a furan-methyl-ene moiety for (I). Hence, mol-ecules of (I) and (II) show similarities in their mol-ecular and crystal structures. The conformation of the central portion of the mol-ecule of (II) is also therefore partially determined by an intra-molecular N-H⋯O hydrogen bond and inter-molecular N-H⋯O hydrogen bonds form chains parallel to the axis. Likewise, the chains are connected into a three-dimensional network by C-H⋯O hydrogen bonds and C-H⋯π(ring) inter-actions.
（I）（CHNO）分子中中心苯环的构象部分由分子内N-H⋯O氢键决定。在晶体中，平行于 轴的链由分子间N-H⋯O氢键产生，这些链通过分子间C-H⋯O氢键和C-H⋯π（环）相互作用组装成三维网络结构。（II）（CHNO）分子与（I）的不同之处仅在于酰肼N原子上的取代基，（II）中存在苯基亚甲基部分，而（I）中为呋喃亚甲基部分。因此，（I）和（II）的分子在分子结构和晶体结构上表现出相似性。所以，（II）分子中心部分的构象也部分由分子内N-H⋯O氢键决定，分子间N-H⋯O氢键形成平行于 轴的链。同样，这些链通过C-H⋯O氢键和C-H⋯π（环）相互作用连接成三维网络。
