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)(4,4'-bipy) ( 3) form supramolecular structures that are unprecedented in organocopper chemistry; one-dimensional chains of copper atoms with Cu center dot center dot center dot 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.
