The easily attainable quadridentate ligand bis‐ N , N ′‐(2‐methylquinoline)‐1,2‐ trans ‐cyclohexanediimine forms double helical dimeric complexes with Cu I and monomeric complexes with Cu II , which are air‐ and moisture‐stable and whose structures have been determined through X‐ray diffraction. In an acetonitrile solution, it is possible to cycle electrochemically between the two forms, through a fast process which can be repeated at will (see diagram).
