Abstract

In the present work, we describe a kind of novel cucurbit[8]uril-based coordination supramolecular self-assembly taking place in the presence of tetrachloride transition-metal dianions ([MtransCl4]2−, Mtrans = Cd, Zn, Cu, Co) in HCl solution. As reported previously, the “honeycomb effect” of the tetrachloride transition-metal dianion ([MtransCl4]2− has been observed in the coordination of strontium cations to cucurbit[8]uril molecules (Q[8]s). It seems that the [MtransCl4]2− anions form a honeycomb structure with hexagonal cells filled with Sr2+–Q[8] linear coordination polymers in which the Sr2+ cations coordinate to Q[8] molecules and form zigzag coordination polymers.
