Cuprophilic and (pi)-stacking interactions in the formation of supramolecular stacks from dicoordinate organocopper complexes

The unsupported organocopper pyridine complexes C6F5Cu(py)(2) and [C6F5Cu]2(4,4ʹ-bipy)(3) form supramolecular structures that are unprecedented in organocopper chemistry; one-dimensional chains of copper atoms with Cu-Cu distances of 2.8924(3)(angstrom) in the blue-luminescent complex 2 are likely associated with cuprophilic interactions, whereas multiple perfluoroarene-arene interactions dominate in the supramolecular assembly of 3.
