氮杂俘精酸酐作为光致变色材料近年来已引起人们的极大兴趣,但其晶体结构数据还未见报导.测定它们的晶体结构,研究其结构与性能的关系,有着非常重要的意义.本文测定了标题化合物(Ⅰ)和(Ⅱ)的结构。实验1.从氯仿和石油醚的混合溶剂中培养出黄色单晶.在Nicolet R 3m/E 四圆衍射仪上收集衍射强度数据.用石墨单色器单色化的Mo Kα射线作辐射光源,以θ/2θ扫描方式收集2θ3～50°范围的数据.强度数据没有进行吸收校正.有关晶体数据列于表1中。
As a photochromic material, aza-fulgide has drawn great interest in recent years, but its crystal structure data have not been reported yet.It is very important to determine their crystal structure and to study the relationship between structure and properties. The structures of the title compounds (I) and (II) were determined. Experiment 1. The yellow single crystal was grown from a mixed solvent of chloroform and petroleum ether. The diffraction intensity data were collected on a Nicolet R 3m / E four-circle diffractometer. Mo Ka radiation monochromatized with a graphite monochromator was used as a radiation source, Data in the range of 2θ3 to 50 ° were collected by the θ / 2θ scan method, and the intensity data were not subjected to absorption correction.
