Abstract
In this study, complexes {[Pb4(C30H30N20O10)2Cl2]Cl2(H2O)2}PbCl6 · 12H2O (1) and [Hg(C30H30N20O10)Cl2] · 6H2O (2) have been synthesized and structurally characterized. Single-crystal X-ray diffraction analyses reveal that water-soluble toxic metal ions, Pb2+ and Hg2+, can be chelated by cucurbit[5]uril to form molecular capsule and molecular bowl. Moreover, solid-state packing of these molecular capsule or molecular bowl shows the formation of a channel, in which octahedral [PbCl6]4− or tetrahedral [HgCl4]2− anions were encapsulated.
