The title compound, C(16)H(15)Cl(2)N(3)O(2)·CH(3)OH, a Schiff base molecule, is prepared by the reaction of 3,5-dichloro-salicyl-aldehyde with 4-dimethyl-amino-benzohydrazide in methanol. The Schiff base mol-ecule is approximately planar, with a mean deviation from the least-squares plane defined by the non-H atoms of 0.0452 (3) Å, and with a dihedral angle between the benzene rings of 4.2 (3)°. This planarity is assisted by the formation of an intra-molecular O-H⋯N hydrogen bond. In the crystal, adjacent Schiff base mol-ecules are linked by two methanol mol-ecules through N-H⋯O and O-H⋯O hydrogen bonds, forming dimers.
标题化合物C(16)H(15)Cl(2)N(3)O(2)·CH(3)OH是一种席夫碱分子，通过3,5-二氯水杨醛与4-二甲基氨基苯甲酰肼在甲醇中反应制备而成。席夫碱分子近似平面状，非氢原子所定义的最小二乘平面的平均偏差为0.0452 (3) Å，苯环之间的二面角为4.2 (3)°。这种平面性通过分子内O-H⋯N氢键的形成得以辅助。在晶体中，相邻的席夫碱分子通过两个甲醇分子经由N-H⋯O和O-H⋯O氢键相连，形成二聚体。
