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 (see figure). 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.
