摘要

在标题化合物C17H18N2O7·H2O的结构中，氢键将三个分子连接到水分子上。额外的氢键相互作用通过酰胺氮供体和两个甲基氧受体连接两个分子。这种三维氢键网络没有特定的方向性，并且观察到两个甲氧基的轻微紊乱。根据力场计算，较弱但扩展更广的范德华相互作用比氢键相互作用表现出更大的稳定效应，而氢键分析表明，化合物的多晶态可能在未来被发现。

Synthesis and structure of (E)-3,4,5-trihydroxy-N′-(3,4,5-trimethoxybenzylidene)benzohydrazide monohydrate

In the structure of the title compound, C₁₇H₁₈N₂O₇·H₂O, relatively strong bifurcated and simple hydrogen-bond interactions are present, together with extended van der Waals interactions. A hydrogen-bond coordination analysis suggests that polymorphs of the title structure may exist.

In the structure of the title compound, C₁₇H₁₈N₂O₇·H₂O, hydrogen bonds link three molecules to the water molecule. Additional hydrogen-bonding interactions connect two molecules via the amide nitrogen donor and two methoxy oxygen acceptors. This three-dimensional hydrogen-bond network has no particular directionality, and a slight disorder of two methoxy groups is observed. According to force-field calculations, weaker but more extended van der Waals interactions show a larger stabilization effect than the hydrogen-bond interactions, while hydrogen-bond analysis suggests that polymorphs of the compound may be found in the future.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
