    Reactions of [Cp*MCl2](2) with meso-or rac-dpmppm in the presence of NH4PF6 afforded mixtures of stereoisomers formulated as [(Cp*MCl)(2)(meso- or rac-dpmppm)](PF6)(2), from which the major isomers, rac-M-2-[(Cp*MCl)(2)(meso-dpmppm)](PF6)(2) (M = Rh (1a), Ir (1b)) and rac-M-2-[(Cp*MCl)(2)(rac-dpmppm)](PF6)(2) (M = Rh (2a), Ir (2b)), were isolated and characterized by IR, UV-vis, ESI mass, and H-1 and P-31H-1} NMR spectroscopy and X-ray crystallography, where dpmppm is bis[(diphenylphosphino-methyl) phenyl] phosphino}methane and Cp* is eta(5)-pentamethylcyclopentadienyl. The isomeric tetra-phosphine incorporates two Cp*MCl} fragments with four-membered chelation through a pair of outer and inner phosphine units, and fixes them ca. 6.9 angstrom apart from each other. The configurations around the metal centers in 2 were determined to avoid repulsive interaction between the phenyl group on the inner P atom and the M-bound chloride anion, while those in 1 would be determined by minimizing not only the Ph/Cl repulsion but also repulsion between the two metal fragments. In the dichloromethane solutions, the major isomers 1 and 2 were not converted to any other minor isomers even at high temperature, but in dmf and dmso, only 1a was readily transformed into the minor isomer, meso-M-2-[(Cp*RhCl)(2)(meso-dpmppm)](PF6)(2). Cyclic voltammograms of 1a, b and 2a, b demonstrated two irreversible 2e reduction waves corresponding to (MMIII)-M-III -> (MMIII)-M-I -> (MMI)-M-I, in which the mixed-valence states with meso-dpmppm could be stabilized to a larger extent than with rac-dpmppm. Complex 1a heated in acetonitrile with AgOTf/NH4OTf afforded a Rh2Ag2 mixed-metal complex, [(Cp*Rh(CH3CN))(2)Ag-2(OTf)(2)(meso-dpmppm)(2)](OTf)(4) (5). (C) 2015 Elsevier B.V. All rights reserved.
