an approximately planar four-membered ring structure. The structure of compound 6 was determined by X-ray crystallography: orthorhombic, space group Pbca, a= 10.1920(21), b= 13.0615(20) and c= 22.050(5)Å. In order to rationalize the structures of 5 and the cation F3C[graphic omitted]CF3+, ab initio calculations were made on model compounds in which the CF3 groups were replaced by a fluorine atom (i
盐N(SECL)2 +的SbCl 6 - 1和N(SECL)2 +的FeCl 4 - 2通过SECL的反应合成的3 + X -(X =的SbCl 6或的FeCl)与N(森达3)3 ; Se 2 NCl 3与SbCl 5反应也形成图1。的反应1用的SnCl 2和F 3 CCCCF 3导致F的形成3 C [图形省略] CF 3+ SbCl 6 – 3。在该反应中,Se 2 N +阳离子可能是中间体,因为SnCl 2似乎是第一步反应中提取氯所必需的,以原位生成Se 2 N +,然后添加F 3 CCCCF 3生成3。化合物3是产生硒化合物的有用组成部分,例如F 3 C [省略图] CF 3 4,F 3 C [省略图] CF 3 5和F 3 C [省略图] CF3 6。通过电子衍射显示杂环5具有近似平面的四元环结构。化合物6的结构通过X射线晶体学测定:正交晶,空间群Pbca, a= 10.1920(21),
