Abstract

The asymmetric unit of the title compound, 2C(11)H(14)N(2)O(3)·C(16)H(16)N(2)O(4), contains one mol-ecule of 2-hydr-oxy-4-methyl-N-propanoylbenzohydrazide and one-half of a mol-ecule of 2-hydr-oxy-N-(2-hydr-oxy-4-methyl-benzo-yl)-6-methyl-benzohydrazide. The latter is located on a centre of inversion. Intra-molecular N-H⋯O inter-actions stabilize the conformations of both mol-ecules. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.

摘要

标题化合物2C₁₁H₁₄N₂O₃·C₁₆H₁₆N₂O₄的不对称单元包含一个2-羟基-4-甲基-N-丙酰基苯甲酰肼分子和半个2-羟基-N-(2-羟基-4-甲基苯甲酰基)-6-甲基苯甲酰肼分子。后者位于一个对称中心上。分子内N-H⋯O相互作用稳定了两个分子的构象。晶体结构通过分子间N-H⋯O和O-H⋯O氢键得以稳定。
