    A series of metal complexes with the non-innocent N,N?-Bis(pentafluorophenyl)-o-phenylenediamido ligand: twisted geometry for tuning the electronic structure

  • Original language description

    A series of homoleptic complexes with non-innocent ligands derived from N,N? -bis(pentafluorophenyl)-o-phenylenediamine (H2Fpda) are reported. [NiII(Fsbqdi)2] (1), [PdII(Fsbqdi)2] (2), [CoII(Fsbqdi)2] (3), and [CuII(Fsbqdi)2] (4) were synthesized, where(Fsbqdi)1- represents a radical anion formed by one-electron oxidation of the doubly deprotonated H2Fpda. Complex 4 is the first CuII complex where both o-phenylenediamine derived ligands are monoanionic radicals. The electronic structures of the neutralcompounds 1-4 and of some of their cationic and/or anionic neighboring redox states were probed using EPR and UV-VIS-NIR spectroelectrochemistry. The twisted geometry of the complexes results in considerable changes in their electronic structures compared to the well known square-planar complexes.

    Řada kovových komplexů s non-innocent ligandem N,N'-Bis(pentafluorofenyl)-o-fenylendiamido: nastavení elektronové struktury vlivem zkroucené geometrie

  • Czech description

    Řada homoleptických komplexů s non-innocent ligandy odvozených od N,N' -bis(pentafluorofenyl)-o-fenylenediamine (H2Fpda) je popsána. [NiII(Fsbqdi)2] (1), [PdII(Fsbqdi)2] (2), [CoII(Fsbqdi)2] (3), a [CuII(Fsbqdi)2] (4) byl syntetizovány, kde (Fsbqdi)1- reprezentuje radikálový anion vytvořený jednoelektronovou oxidací dvojnásobně deprotonovaného H2Fpda. Komplex 4 je první CuII komplex, kde oba o-fenylenediaminové ligandy jsou monoanionickými radikály. Elektronové struktury neutrálních sloučenin 1-4 a některých jejich kationických a anionických redox stavů byly prověřeny s použitím EPR a UV-VIS-NIR spektroelektrochemie. Zkroucená geometrie komplexů způsobuje značné změny v jejich elektronových strukturách ve srovnání se známými čtvercově-planárními komplexy.
