Reaction of 1,2-bis(diphenylphosphino)benzene (dppbz) with PhpdtFe(2)(CO)(6) (A) in hot acetonitrile yielded a chelated complex, PhpdtFe(2)(CO)(4)((2)-dppbz) (1), in moderate yield. Further treatment using an excess of HBF4Et2O resulted in the protonation of 1 at room temperature in dichloromethane solution, forming a hydride [Phpdt(-H)Fe-2(CO)(4)((2)-dppbz)]BF4 (2). The chemical structures of both complexes were fully characterized by spectroscopic methods and X-ray crystallography, and the electronic structures were further investigated by UV-vis spectroscopy. The cyclic voltammetry (CV) of 1 in the absence and presence of acetic acid were also investigated. @@@ [GRAPHICS] @@@ .
