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.
