Syntheses and characterization of [(η6-C6Me6)Ru(μ-N3)(X)]2 (X=N3 and Cl) complexes and their reactions towards mono- and bidentate ligands

The reaction of the complex [{(η6-C6Me6)Ru(μ-Cl)Cl}2] 1 with sodium azide ligand gave two new dimers of the composition [{(η6-C6Me6)Ru(μ-N3)(N3)}2] 2 and [{(η6-C6Me6)Ru(μ-N3)Cl}2] 3, depending upon the reaction conditions. Complex 3 with excess of sodium azide in ethanol yielded complex 2. These complexes undergo substitution reactions with monodentate ligands to yield monomeric complexes of the type [(η6-C6Me6)Ru(X)(N3)(L)] {X=N3, Cl, L=PPh3 …
