Phenyl-functionalized diiron propanediselenolato complexes containing intramolecular bridging diphosphine ligands

Reactions of [(-SeCH2)(2)CHC6H5]Fe-2(CO)(6) (A) with 1,1-bis(diphenylphosphino)ferrocene (dppf) or 1,3-bis(diphenylphosphino)propane (dppp) in refluxing xylene yielded [(-SeCH2)(2)CHC6H5]Fe-2(CO)(4)(-dppf) (1) or [(-SeCH2)(2)CHC6H5]Fe-2(CO)(4)(-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). [GRAPHICS] .
