Synthesis, characterization and molecular structure of the [(η 6-C 6Me 6)Ru(μ-N 3)(N 3)] 2 complex and its reactions with some monodentate ligands

Abstract

The reaction of complex [(η 6-C 6Me 6)Ru(μ-Cl)Cl] 2 ( 1) with sodium azide yielded complexes of the composition [(η 6-C 6Me 6)Ru(μ-N 3)(N 3)] 2 ( 2) and [(η 6-C 6Me 6)Ru(μ-N 3)(Cl)] 2 ( 3), depending upon the reaction conditions. Complex 3 with excess of sodium azide in ethanol yielded complex 2. Complexes 2 and 3 undergo substitution reactions with monodentate ligands such as PPh 3, PMe 2Ph and AsPh 3 to yield monomeric complexes. The structure of complex 2 was determined by X-ray crystallography. All these complexes were characterized by micro analytical data and by FT-IR and FT-NMR spectroscopy. Complex 2 crystallizes in the monoclinic space group P2 1/ n with a = 8.5370(11) Å, b = 16.192(2) Å, c = 10.4535(13) Å and β = 110.877(2)°.
