A new dinuclear ruthenium complex bridged by azide: [Ru₂Cl₂(μ-1,3-N₃)₂(Me₂SO)₆]

Reaction of [RuCl2(Me2SO)(4)] with sodium azide in water affords the title complex di-mu-1,3-azido-bis[chlorotris(dimethyl sulfoxide-kappaS) ruthenium(II)], [Ru2Cl2(N-3)(2)(C2H6-OS) 6]. X-Ray crystal structure determination has been performed on the title compound. The result reveals that two [Ru(Me2SO)(3)](2+) units are linked by two bridging azide ligands to form a centrosymmetric complex. The geometry about each Ru atom is essentially octahedral, with three S atoms of Me2SO arranged in a facial configuration, two coordinated N atoms of bridging N-3(-) ligands and a chloride anion.
