摘要

本研究描述了七种新型对称和不对称双腙衍生物的构象多态性，这些衍生物含有柔性的CN-NC-CN-NC脊柱。从计算研究中得到提示，缓慢蒸发的溶剂介导结晶产生了化合物的多晶型。溶剂的选择决定了本研究中化合物的多晶的形成，无论是伴随的还是单独的。用单晶x射线衍射技术对所有晶型进行了结构表征。

Polymorphism in novel symmetric and asymmetric bis-hydrazone derivatives†

This study describes conformational polymorphism in seven novel symmetric and asymmetric bis-hydrazone derivates, which contain a flexible CN–NC–CN–NC spine. Taking a cue from the computational study, solvent-mediated crystallization by slow evaporation generated polymorphs of the compounds. The choice of solvent determines the formation of polymorphs of the compounds in this study either concomitantly or exclusively. All the polymorphs have been characterized structurally by single crystal X-ray diffraction technique.
