An unusual copper(I) complex of a new macrocyclic ligand
Abstract
The new 18-membered macrocyclic ligand 1,5(2,6)dipyridina-3,7(1,4)dipiperazinaoctacyclophane, † shows an allosteric effect upon complexation with copper(I) chloride in aqueous ethanol resulting in an extraordinary copper complex, the structure of which has been established by X-ray diffraction analysis.
