  摘要：

  Irradiation of a mixture of tungstenocene or molybdenocene dihydride and a metal-metal-bonded dimeric complex has been found to be a convenient route to homo- and heterometallic complexes. The photoreactions of (eta(5)-C5H5)(2)M(1)H(2) With [(eta(5)-C5H5)M(2)(CO)(3)](2) (M(1), M(2) = W, Mo) in DME afford in good yields the bimetallic complexes (eta(5)-C5H5)(CO)M(1)(mu,sigma-eta(5)-C5H4)-M(2)(CO)(2)(eta(5)-C5H5) with a M(1)-M(2) bond. (1a, M(1) = W, M(2) = Mo; 1b, M(1) = Mo, M(2) = W; 1C, M(1) = M(2) = W; 1d, M(1) = M(2) = MO). BY use of [(eta(5)-C(5)R(5))Ni(CO)](2) as the dimer part, the heterobimetallic hydrides (eta(5)-C5H5)(2)M(mu-H)(mu-CO)Ni(C(5)R(5)) (2a, M = W, R = H; 2b, M = W, R = Me; 2c, M = Mo, R = H, 2d, M = Mo, R = Me) were obtained, where the two metallocene cyclopentadienyl rings remain intact and the metal-metal bond is bridged by CO and hydride. Similar photolysis of a mixture of (eta(5)-C5H5)(2)MH(2) and [(eta(5)-C5H5)Ru(CO)(2)](2) has afforded two trimetallic complexes: (eta(5)-C5H5)(mu,sigma-eta(5)-C5H4)M(mu-CO)(2)Ru(eta(5)-C5H5)Ru(eta(5)-C5H5)-(CO)H (3a, M = W; 3b, M = Mo), where the Ru-Ru bond still exists with a new M-Ru bond and one bridging (mu,sigma-eta(5)-C5H4) ring between M and the other Ru, and (mu,sigma-eta(5)-C5H4)(2)-Mh(2)[(eta(5)-C5H5)Ru(CO)](2) (4a, M = W; 4b, M = Mo), in which both of the cyclopentadienyl rings of the metallocene are metalated with Ru. The crystal and molecular structures of 1a, 2d, 3a, and 4a have been determined by single-crystal X-ray diffraction analysis.
