Abstract: A novel group of potassium-containing 1-D coordination polymers demonstrates the importance and role of K—Cπ interactions. [K(Odpp)]∞, 1, (Odpp = 2,6-diphenylphenolate) forms a ladder-type polymer where extensive K—Cπ interactions provide additional coordinative saturation. {[K2(Odpp)2H2O]2}∞, 2, consists of tetrameric cores of K4O6 polyhedra linked via a network of K—Cπ interactions. Compound 2 displays not only inter- and intramolecular K—Cπ contacts, but also several K—H agostic interactions that provide further coordinative saturation.
