Abstract

The interaction between symmetric tetramethyl cucurbit[6]uril (TMeQ[6]) and 2,3-dimethylphenylpiperazine hydrochloride (PMY) has been studied in the presence of [CdCl4]2-. Each port of the TMeQ[6] is connected to PMY through weak interactions such as ion dipole interactions and C-H···O hydrogen bonding interactions, whilst the [CdCl4]2- is connected with the portal carbonyl oxygen, glycoside urea methylene and a bridging methylene of a TMeQ[6] molecule via ion-dipole interactions. These interactions were evident from a single crystal X-ray diffraction study of TMeQ[6]-PMY-[CdCl4]2-. In addition, the complex can form a one-dimensional supramolecular chain structure, and then assemble into a two-dimensional supramolecular framework, which can be described as a TMeQ[6]-PMY-[CdCl4]2- based supramolecular framework (QSF).
