New platinum compounds containing the diphosphine ligand 2-(ferrocenylidene)-4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (fbpcd): Synthesis, redox behavior, and X-ray diffraction structures Of PtCl2(fbpcd) and Pt(mnt)(fbpcd)

Journal Article · · Polyhedron

The reaction of the redox-active diphosphine ligand 2-(ferrocenylidene)-4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (fbpcd) with PtCl2(1,5-cod) furnishes the platinum(II) compound PtCl2(fbpcd) (2). Treatment of 2 with disodium maleonitriledithiolate (Na(2)mnt) yields the chelating thiolate compound Pt(mnt)(fbpcd) (3). Both 2 and 3 have been fully characterized in solution by IR, UV-Vis, and NMR spectroscopies, and their molecular structures established by X-ray crystallography. The redox properties of the fbpcd ligand and compounds 2 and 3 have been investigated by cyclic voltammetry, and the composition of the HOMO and LUMO levels in these systems have been determined by extended Huckel MO calculations, the results of which are discussed with respect to electrochemical data.
