The new cluster [HRu3(CO)10(C7H8N)] was synthesized by the reaction of dodecacarbonyltriruthenium with p-toluidine in benzene. The complex was characterized by IR, 1H NMR, 13C NMR and elemental anal. 1H NMR shows that the cluster contains ruthenium bonded hydrogen. An x-ray diffraction anal. of the cluster has unequivocally established its structure. The cluster crystallizes in the monoclinic system, space group P21/c, a 1.3816(2), b 0.9941(2); c 1.6005(2) nm, a = g 90.00(0)? b 98.39(1)? Z = 4, m = 20.70 cm-1, dc = 2.11 g/cm3, F(000) = 1320, final R = 0.0311 and Rw = 0.0283 based on 3790 independent reflections with I>3s(I).
