Reactions of Ruthenium Complexes Having Pyridyl-Containing Ligands, 2-Pyridinecarboxylato and 2,2'-Bipyridine, with an Azide Ion: Formation of Nitrido-Bridged Diruthenium Complexes
Reactions of ruthenium complexes having 2-pyridinecarboxylato and 2,2'-bipyridine ligands with sodium azide in alcohol afforded nitrido-bridged diruthenium complexes, [{Ru(OR)(pyca)(bpy)}(2)(mu-N)](+) (R = CH3, C2H5). Diruthenium complexes showed diamagnetic properties, a linear Ru-N-Ru coordination configuration, and two irreversible oxidation waves and two reversible reduction waves.
