用X射线衍射法测定了N-（4-硝基亚苄基）苯胺（1）、N-（4-氯亚苄基）-4-甲基苯胺（2）和N-（4-甲基亚苄基）-4-甲基苯胺（3）在不同温度下的晶体结构。在所有化合物的晶体结构中观察到动态无序。动态无序是根据涉及晶体中踏板运动的构象变化来解释的。
The crystal structures of N-(4-nitrobenzylidene)aniline (1), N-(4-chlorobenzylidene)-4-methylaniline (2) and N-(4-methylbenzylidene)-4-methylaniline (3) were determined by X-ray diffraction analyses at various temperatures. A dynamic disorder was observed in the crystal structures of all compounds. The dynamic disorder is accounted for in terms of a conformational change involving a pedal motion in the crystals.
