The X-ray crystal structures of two isomeric cyclotrisilanes, cis–cis-and cis–trans-1,2,3-tri-t-butyl-1,2,3-trimesitylcyclotrisilanes (1a) and (1b), respectively, have been determined; the structure of (1b) reveals that one Si–Si bond is significantly longer than the other two in agreement with the recently reported chelotropy of photo-cleavage of (1b) to give E-and Z-1,2-di-t-butyl-1,2-dimesityldisilenes
两种同分异构的环三硅烷的X射线晶体结构分别为顺式-顺式和顺式-1,2,3-三叔丁基-1,2,3-三甲苯基环三硅烷(1a)和(1b)被确定;(1b)的结构表明,一个Si-Si键比其他两个键长得多,这与最近报道的(1b)的光裂解使E-和Z -1,2-di-t-丁基1,2-二甲二甲苯基(2a)和(2b)。
