Novel Supramolecular Assemblies Based on[CdCl_4]~2-Induced Coordination of Lanthanide Metal Ions to Cucurbit[5]uril

【摘要】：正In one of our previous works,we used to report a crystal structure of a compound of hydronium dichloroferrate chloride adducts with cucurbituril,we found that it is a novel supramolecular architecture of trans-[FeCl_2(H_2O)_4]~+ with Q[6].In the Ln~(3+)-Q[6]and Ln~(3+)-Q[7]systems,the[MCl_4]~(2-)(M=Cd,Zn) can present the"honeycomb effect"and form the honeycomb hallows in which the one-dimensional supramolecular chains or tubes constructed of Ln~(3+)cations and Q[6]or Q[7]molecules through direct
