Abstract

The complexes [Rh2L4{µ-2,3-(NH)2C10H6}][1; L2=(CO)(PPh3) or η4-cod (cyclo-octa-1,5-diene)] and [Rh2L4{µ-1,8-(NH)2C10H6}][2; L2=(CO)(PPh3), η4-cod, η4-nbd (norbornadiene), or η4-tfbb (tetrafluorobenzobarrelene)] undergo two sequential one-electron oxidations at a platinum bead electrode. At –78 °C, the chemical oxidation of compound (1; L2=η4-cod) or (2; L2=η4-cod) in thf, with [CPh3][BF4] in CH2Cl2, gives the [Rh2]3+-containing salts [Rh2(η4-cod)2(η-L1)][BF4][1+; L1= 2,3-(NH)2C10H6 or 2+; L1= 1,8-(NH)2C10H6] which, in tetrahydrofuran (thf)-CH2Cl2 mixtures at –196 °C, show solvent-dependent e.s.r. spectra implying thf co-ordination at one axial site. The irreversible one-electron reduction of [Rh2(NO)(η4-cod)2{µ-1,8-(NH)2C10H6}][PF6](3), prepared from (2;L2=η4-cod) and [NO][PF6] in CH2Cl2, leads to the loss of NO and the regeneration of (2; L2=η4-cod).
