Effect of noncovalent complexations on coordination interactions in a tricomponent system of β-cyclodextrin, copper chloride and hexamethylene tetramine

This study reveals that the noncovalent complexation between β-CD and Cu(HMTA)2+ makes a positive contribution to the coordination interaction between Cu2+ and HMTA in a tricomponent system. Besides, mono- and binuclear complexes: [β-CD·Cu]+ and [Cu·β-CD·Cu]+ were observed under the condition of ESI-MS.
