New cluster [ HRu3(CO)10(C7H8N)] was synthesized by the reaction of decacar-bonyltriruthenium with p-toluidine in benzene. The structure was characterized by IR, 1H NMR, 13C NMR and elemental analysis. 1H NMR show that the cluster contains ruthenium-hydrogen end bond, An X-ray diffraction analysis of the cluster has unequivocally established its structure. The cluster crystallizes in the monoclinic system, space group P21/ c, a= 1.3816(2)nm, b = 0.9941(2)nm; c=1.6005(2)nm, α=γ= 90.00(0)°,β=98.39(1)ooooooo , V=2.1747(6)nm3, Z=4, μ= 20.70cm-1, Dc=2.11g/cm3, F(000)=1320, final R = 0.0311 and Rw = 0.0283 based on 3790 independent reflections with I>3σ(I).
