Abstract: | Heterometallic Complexes with E6 Ligands (E = P, As) The reaction of [Cp*Co(μ-CO)]2 1 with the sandwich complexes [Cp*Fe(η5-E5)] 2 a: E = P, 2 b: E = As in decalin at 190°C affords besides [Cp Co2E4] 4: E = P, 7: E = As and [Cp Fe2P4] 5 the trinuclear complexes [(Cp*Fe)2(Cp*Co)(μ-η2-P2)(μ3-η1:2:1-P2)2] 3 as well as [(Cp*Fe)2(Cp*Co)(μ3-η2:2:2-As3)2] 6 . With [Mo(CO)5(thf)] 3 and 6 form in a build-up reaction the tetranuclear clusters [(Cp*Fe)2(Cp*Co)E6{Mo(CO)3}] 10: E = P, 11: E = As. 3, 6 and 11 have been further characterized by an X-ray crystal structure determination. |
