Invariant Oxidation State of Copper but not of Ruthenium in Complexes with Noninnocent N-(2-Methyl-5,8-dioxo-5,8-dihydroquinolin-7-yl)acetamide: A Combined Structural, Electrochemical and Spectroelectrochemical Investigation
Popis výsledku v původním jazyce
The compounds [(dppf)Cu(L)](BF4) (1[BF4]) [dppf = 1,1-bis(diphenylphosphanylferrocene), L = N-(2-methyl-5,8-dioxo-5,8-dihydroquinolin-7-yl)acetamide] and [(acac)2Ru(L)] (2) (acac = acetylacetonato) were prepared from the reactions of [Cu(dppf)(CH3CN)2](BF4) or [Ru(acac)2(CH3CN)2], respectively with L. Structural characterization of 1[BF4] shows a distorted tetrahedral coordinated copper center. Both complexes show one-electron reversible oxidation as well as reduction processes in their cyclic voltammogram. The first oxidation process of 1[BF4] leads to absorptions at around 900 nm in the UV/Vis/NIR spectrum and results in an EPR silent species up to 110 K thus indicating a dppf-centered oxidation. The reduction processes of 1[BF4] show features in theUV/Vis/NIR, IR as well as EPR spectrum that are compatible with L-centered redox processes. In contrast to this, the ruthenium complex 2 shows metal-centered spin in both the one-electron oxidized as well as reduced forms.
