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 [Cp2*Co2E4] 4: E = P, 7: E = As and [Cp2*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.
Notes:
Die Umsetzung von [Cp*Co(μ-CO)]2 1 mit den Sandwichkomplexen [Cp*Fe(η5-E5)] 2a: E = P, 2 b: E = As bei 190°C in Dekalin ergibt neben [Cp2*Co2E4] 4: E = P, 7: E = As und [Cp2*Fe2P4] 5 die Dreikernkomplexe [Cp*Fe)2(Cp*Co)(μ-η2:2-P2)(μ3-η1:2:1-P2)2] 3 sowie [(Cp*Fe)2(Cp*Co)(μ3-η2:2:2-As3)2] 6. 3 und 6 reagieren mit [Mo(CO)5(thf)] in einer Aufbaureaktion zu den Vierkernclustern [(Cp*Fe)2(Cp*Co)E6{Mo(CO)3}] 10: E = P, 11: E = As. 3, 6 und 11 wurden zusätzlich durch eine Kristallstrukturanalyse charakterisiert.
