An arene-ruthenium dimeric complex,[(η6-p-cymene)Ru(μ-N3)(N3)]2 1,was synthesized from the reaction of [(η6-p-cymene)Ru(μ-Cl)(Cl)]2 with an excess NaN3 and charac-terized by single-crystal X-ray diffraction. It crystallizes in triclinic,space group P1 with a = 8.2321(8),b = 8.2155(8),c = 9.9976(11) ,α = 81.786(5),β = 82.906(5),γ = 77.134(5)°,V = 649.46(11) 3,Z = 1,Mr = 638.68,Dc = 1.633 g/cm3,μ(MoKα) = 1.195 mm-1,F(000) = 320,S = 0.974,the final R = 0.0282 and wR = 0.0644 for 2363 observed reflections with Ⅰ > 2σ(Ⅰ) and 157 variables. The neutral molecule is dimeric with two azide ligands bridging two ruthenium atoms to adopt an octahedral coordination geometry. The average Ru-Nt (terminal) and Ru-Nb (bridge) bond lengths are 2.092(3) and 2.147(2) ,respectively.
