Abstract
Treatment of (μ3-S)FeCo2(CO)9 (1) with diphenyl-2-pyridylphosphine (2-C5H4NPPh2) or Ph2PN(CH2CHMe2)PPh2 at reflux in toluene resulted in the formation of dicobalt–iron complexes (μ3-S)FeCo2(CO)7(2-C5H4NPPh2) (2) and (μ3-S)FeCo2(CO)7[Ph2PN(CH2CHMe2)PPh2] (3) with bridging bidentate ligands via carbonyl substitution in 51 and 53% yields, respectively. The new complexes 2 and 3 were structurally characterized by elemental analysis, IR and NMR spectroscopy, and X-ray crystallography.
