摘要：

Four new dicobalt-iron cluster complexes with bridging or chelating diphosphine ligands have been prepared and structurally characterized. Treatment of (mu(3)-S)FeCo2(CO)(9) (A) with Ph2PCH2CH2PPh2 at room temperature in CH2Cl2 resulted in formation of [(mu(3)-S)FeCo2(CO)(8)](2)(Ph2PCH2CH2PPh2) (1) and (mu(3)-S)FeCo2(CO)(7)(Ph2PCH2CH2PPh2) (2) with bridging diphosphine ligand in 12% and 56% yields, respectively, whereas (mu(3)-S)FeCo2(CO)(7)(cis-Ph2PCH=CHPPh2) (3) with chelating diphosphine ligand was produced by reaction of A with cis-Ph2PCH-=CHPPh2 in 88% yield. In addition, (mu(3)-S)FeCo2(CO)(7)(Ph2PCH2PPh2) (4) with bridging diphosphine ligand could be obtained by reaction of A with Ph2PCH2PPh2 in 69% yield. The new complexes 1-4 were characterized by elemental analysis, spectroscopy and X-ray crystallography. (C) 2013 Elsevier Ltd. All rights reserved.
