摘要
质子化N,N,N',N'-四苄基乙二胺可与[Fe(CN)6]3-,[SnCl6]2-和[TeCl6]2-二次球形配位分别形成可容纳客体分子的包结物晶体(1)～(3).晶体(1)通过NH+…NC-,NH+…π(NC)和CH…π(NC)组合合成子,构筑了亲水性层柱隧道结构,孔径尺寸为1.03nm×1.12nm,两个乙醇分子和两个水分子填充于隧道中;晶体(2)通过CH…Cl-合成子,构筑了亲水性层间隧道结构,孔径尺寸为0.94nm×0.73nm,三个水分子和两个氯离子填充于隧道中;晶体(3)的结构与晶体(2)相似,也是通过CH…Cl-合成子,构筑了层间亲水性隧道结构,孔径尺寸为0.94nm×0.72nm,两个水分子填充于隧道中。
Protonated N,N,N＇,N＇-tetrabenzyl-ethylenediamine can form inclusion crystals （1）-（3） with [Fe（CN）6]^3-, [SnCl6]^2- and [TeCl6]^2- by second-sphere coordination, respectively. The crystal （1）, through the combination of synthons of NH^＋…NC^- , NH^＋…π（NC） and CH…π（NC）, constructing a hydrophilic pillared layer channel with channel size of 1.03 nm × 1.12 nm, which can accommodate two alcohol molecules and two water molecules; the crystal （2） is endowed with hydrophilic channels between layers through C-H…Cl^- synthons, with channel size of 0.94 nm × 0.73 nm, in which three water molecules and two Cl^- anions are packed; the structure of crystal （3） is similar to that of crystal （2）, a hydrophilic channel between layer structures is constructed by C-H…Cl^- synthons, with channel size of 0.94 nm×0.72 nm, and two water molecules are filled within the channel between layers.
