摘要：

Inter-metal carbonyl exchange in [(eta(5)-C5H5)(2)Mo-2(CO)(6)] and [(eta(5)-C5H5)(2)MoW(CO)(6)], via [(eta(5)C(5)H(5))(2)Mo-2(mu-CO)(2)(CO)(4)] and [(eta(5)-C5H5)(2)MoW(mu-CO)(2)(CO)(4)], has been observed by C-13 NMR spectroscopy. The Delta G(double dagger) for the exchange is 13.9 +/- 0.2 kcal mol(-1) for the gauche isomer of[(eta(5)-C5H5)(2)Mo-2(CO)(6)] and 14.9 +/- 0.2 kcal mol(-1) for the trans isomer.
