Abstract

The compds. [fac-Re(CO)3Cl(L)] and [M(CO)4(L)], M = Cr, Mo, W and L = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene, have been studied electrochem. and spectroelectrochem. (IR, UV-vis-NIR, EPR). The neutral rhenium complex contains an isopropyl-shielded chloride ligand; its reversible oxidn. was shown to involve a largely metal-based HOMO. One electron could be added reversibly to the diimine-based LUMO of all complexes, as evident from EPR spectroscopy. However, there was no evidence for the reversible acquisition of more than one electron by L in these complexes, ruling out an electron reservoir functionality with multielectron reactivity. DFT and TD-DFT calcns. were performed for the [Re(CO)3Cl(L)]n redox series (n = +, 0, -). [on SciFinder(R)]
