摘要：

A new Fe carbonyl cluster [Fe3(CO)6] with a Fe-Fe distance of 0.273 nm, which is longer than that in Fe3(CO)12 (0.262 nm) and in Fe metal (0.248 nm), was prepared by supporting Fe3(CO)12 On SiRx/SiO2(R=CH3, C6H5) followed by treatment at 368 K in vacuum. The Fe clusters on SiMe2/SiO2 showed a higher activity - by a factor of 200 - than the Fe species on SiO2 for propene hydrogenation.
