Starting from MePCl2 the iron complexes (CO)4Fe-PMe(NMe2)2 (1), (CO)4Fe-PMe(NMe2)Cl (2), (CO)4Fe-PMe(NMe2)H (3), and (CO)4Fe-PMe(H)Cl (4) are accessible.Of these the PCl compounds 2 and 4 with carbonyl metalates yield the metal-metal bonded functional dinuclear complexes (μ-PMeNMe2)FeCo(CO)7 (5), (μ-PMeH)FeCo(CO)7 (6a), (μ-PMeH)FeMn(CO)8 (7), and (μ-PMeH)Fe2(CO)6NO (8).In the dinuclear complexes (μ-PRH)FeCo(CO)7 (6, R = Me, tBu) CCl4 or CBr4 effect H/Hal exchange with formation of (μ-PRHal)FeCo(CO)7 (9, Hal = Cl; 10, Hal = Br).Subsequent reaction with carbonyl metalates leads to the trinuclear complexes FeCo(CO)7-(μ-PR)-M' (11, M' = Mn(CO)5; 12, M' = FeCp(CO)2) and/or the mixed metal cluster (μ3-RP)FeCo(CO)6M (13, M = Mn(CO)4; 14, M = FeCp(CO); 15, M = CrCp(CO)2; 16, M = WCp(CO)2).Crystal structure determinations were undertaken for the clusters 13b and 14b.
