(μ-L)RuII(acac)22n, n = 2+, +, 0, -, 2-, with L = 3,3',4,4'-tetraimino-3,3',4,4'-tetrahydrobiphenyl. EPR-supported assignment of NIR absorptions for the paramagnetic intermediates
A complete EPR and UV-visible-NIR spectroelectrochem. characterization was carried out for the series 12+/+/0/-/2- where 1 is (μ-L)RuII(acac)22, L = 3,3',4,4'-tetraimino-3,3',4,4'-tetrahydrobiphenyl. The paramagnetic intermediates are identified as the anion radical (L·-) complex 1·- with a long-wavelength intra-ligand transition at 2160 nm and as the weakly coupled diruthenium(II,III) species 1+ (Kc = 103) with a low-intensity intervalence charge transfer (IVCT) band at 1570 nm. DFT calcns. using ADF and Gaussian 03 programs support these assignments. on SciFinder(R)
