In the title compound, CHINO·CHOH, two aromatic rings are linked by an -substituted hydrazide function. The dihedral angle between the aromatic rings is 10.53 (8)°. The stereochemistry about the imine function is . The methanol mol-ecule forms an O-H⋯O hydrogen bond to the hydrazide O atom. In the crystal, chains of mol-ecules running along the -axis direction are formed by O-H⋯O hydrogen bonds. Adjacent chains are linked through N-H⋯O hydrogen bonds and π-π stacking inter-actions. The inter-molecular inter-actions in the crystal packing were investigated using Hirshfeld surface analysis, which indicated that the most significant contacts are H⋯H (38.2%), followed by C⋯H/H⋯C (20.6%), O⋯H/H⋯O (11.1%) and I⋯H/H⋯I (9.7%).
在标题化合物CHINO·CHOH中，两个芳香环通过一个α-取代的酰肼官能团相连。芳香环之间的二面角为10.53 (8)°。亚胺官能团的立体化学情况为 。甲醇分子与酰肼的O原子形成O—H⋯O氢键。在晶体中，沿a轴方向的分子链通过O—H⋯O氢键形成。相邻的链通过N—H⋯O氢键和π-π堆积相互作用相连。使用 Hirshfeld 表面分析研究了晶体堆积中的分子间相互作用，结果表明最显著的接触是H⋯H（38.2%），其次是C⋯H/H⋯C（20.6%）、O⋯H/H⋯O（11.1%）和I⋯H/H⋯I（9.7%）。
