摘要：
Coordination in supramolecular assemblies formed in aqueous HCl solution was investigated by reacting alkali cations (M+) and inverted cucurbit[6]uril (iQ[6]) in the presence of the structure-directing agent tetrachloride zincate anion ([ZnCl4](2-)). Single-crystal X-ray diffraction analysis revealed that the iQ[6]-M+-[ZnCl4](2-)-HCl interaction systems yielded a supramolecular assembly consisting of iQ[6]/M+-based linear coordination polymers residing within the pores of a honeycomb-like framework of [ZnCl4](2-) anions. Close inspection revealed that different iQ[6]/M+/[ZnCl4](2-)-based supramolecular assemblies (M=Na, K, Rb) presented different porous conformations and displayed different absorption properties.
