Abstract

The structure of the title compound, 4C₂₂H₂₈N₂O₃·C₂H₆O, exhibits a one-dimensional pore structure composed of channels formed by molecules having an acylhydrazone segment connecting a 3,5-di-tert-butylphenol unit and a 2-hydroxyphenol unit. The channels contain disordered ethanol molecules.

In the structure of the title compound, 4C₂₂H₂₈N₂O₃·C₂H₆O, molecules composed of an acylhydrazone segment bridging a 3,5-di-tert-butylphenol unit and a 2-hydroxyphenol unit form columnar quartet channels along the a-axis, within which disordered ethanol solvent molecules reside in two inversion-centre-related positions. Intermolecular hydrogen bonds assemble the channels between the columnar molecules through the hosted ethanol molecule, complemented by weaker van der Waals-type interactions. These weak van der Waals interactions also hold the columns together. Additionally, the title compound demonstrated notable thermal stability at temperatures of up to 251°C. The sharp melting point peak observed in the DSC confirmed its crystalline structure.

N'-[(E)-3,5-二叔丁基-2-羟基苯基-二叔丁基]-2-羟基苯并肼乙醇季溶剂的合成、晶体结构和热性能

在标题化合物4C22H28N2O3·c2h60的结构中，由连接3,5-二叔丁基苯酚单元和2-羟基苯酚单元的酰基腙段组成的分子沿a轴形成柱状四方通道，其中无序乙醇溶剂分子位于两个与倒置中心相关的位置。分子间氢键通过宿主乙醇分子聚集柱状分子之间的通道，并辅以较弱的范德华式相互作用。这些弱的范德华相互作用也使柱保持在一起。此外，标题化合物在高达251°C的温度下表现出显著的热稳定性。DSC中观察到的尖锐的熔点峰证实了其晶体结构。
