Fig. 4: Representation of the crystal structure of macrocycle 11.

Single crystals were grown from a dichloromethane/acetonitrile saturated solution by slow evaporation. Carbon atoms are shown in gray, nitrogen in blue, oxygen in red, ruthenium in turquoise and chlorine in green. Hydrogen atoms are omitted for clarity purposes. Ellipsoids are drawn at 50% probability levels. CCDC ID 1988009.
