摘要：

Three new monophosphine-substituted iron carbonyl cluster complexes [(mu-PDT)Fe-2(CO)(5)L] [(PDT = SCH2CH2CH2S, L = P(CH2Ph)(3), 1; P(C6H11)(3), 2; PPh2(PhMe-p), 3)], which can be regarded as active site mimics for [FeFe]-hydrogenase, have been prepared in 40-70 % yields by reactions of the parent complex (mu-PDT)Fe-2(CO)(6) (A) with monophosphine ligands in the presence of the decarbonylating agent Me3NO center dot 2H(2)O. All three complexes were characterized by elemental analysis and spectroscopic techniques, as well as by X-ray crystallography for complex 1. The IR spectra of the complexes reveal that the electron-donating abilities of the different monophosphine ligands follow the order PPh2(PhMe-p) > P(C6H11)(3) > P(CH2Ph)(3).
