[CdCl_4]~2-Induced Coordination and Supramolecular Self-Assembly of Lanthanide Metal Ions to Cucurbit[6]uril

【摘要】：正In the Ln~(3+)-Q[6]systems,the[CdCl_4]~(2-)can also present the"honeycomb effect"like in the Ln~(3+)-Q[7] systems and form the honeycomb hallows in which the one-dimensional supramolecular chains or tubes constructed of Ln~(3+) cations and Q[6]molecules through direct coordination.A overall view of the coordination feature and the supramolecular assembly in this compound is given in Figure la as a
