Cuprophilic and π-stacking interactions in the formation of supramolecular stacks from dicoordinate organocopper complexes

Abstract

The unsupported organocopper pyridine complexes C₆F₅Cu(py) (2) and [C₆F₅Cu]₂(4,4′-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) Å in the blue-luminescent complex 2 are likely associated with cuprophilic interactions, whereas multiple perfluoroarene–arene interactions dominate in the supramolecular assembly of 3.
