Metal-Mediated Self-Assembly of π-Bonded Benzoquinone Complexes into Polymers with Tunable Geometries

Abstract
Coordination of Mn(CO)3+ to the π system in hydroquinone facilitates proton loss to afford benzoquinone complexes. Subsequent σ coordination of the benzoquinone oxygen atoms to added metal ions results in neutral one-, two-, or three-dimensional quinoid polymers. The geometrical requirements of the metal ion and the presence of added "spacer" ligands dictate the type of polymer formed.
