Unexpected isolation and structural characterization of a redox-active Fe(II) piano-stool complex with an eta(1)-dppe ligand

摘要

A new cationic complex [(eta(2) -bipy)(eta(5)-C5Me5)Fe(eta(1)-dppe)][BPh4] featuring a pendant free diphenylphosphine arm has been isolated in good yield after reaction of 2,2'-bipyridine with the known chloro precursor complex (eta(2)-dppe)(eta(5)-C5Me5)FeCl in presence of NaBPh4. This complex which can be envisioned as a new redox-active building-block has been structurally characterized. (c) 2006 Elsevier B.V. All rights reserved.
