Abstract: | Reactions of [(μ-SeCH2)2CHC6H5]Fe2(CO)6 (A) with 1,1′-bis(diphenylphosphino)ferrocene (dppf) or 1,3-bis(diphenylphosphino)propane (dppp) in refluxing xylene yielded [(μ-SeCH2)2CHC6H5]Fe2(CO)4(μ-dppf) (1) or [(μ-SeCH2)2CHC6H5]Fe2(CO)4(μ-dppp) (2) in moderate yields. The chemical structures of both complexes were characterized by spectroscopic methods and X-ray crystallography, and the electronic structures were further investigated by UV–vis. The redox properties of both complexes in the absence and presence of acetic acid were observed by cyclic voltammetry (CV). |
