Synthesis, structure and electrochemistry of (ferrocene-2-propenoato-O,O′)bis[1,2-bis(diphenylphosphino)ethane-P,P′]ruthenium(II) hexafluorophosphate

The complex [Ru(η2-fcpe)(dppe)2](PF6) (1), where fcpe = ferrocene-2-propenoate and dppe = 1,2-bis(diphenylphosphino)ethane, was synthesized via a “dimer disassembly” method and characterized using elemental analysis, IR spectroscopy, 1H and 31P NMR and X-ray crystallography. The redox potentials of the metal centers were assessed using cyclic voltammetry and Osteryoung square-wave voltammetry. No significant metal–metal interactions were found.
