Biomimetic mono- and dinuclear Ni(I) and Ni(II) complexes studied by X-ray absorption and emission spectroscopy and quantum chemical calculations

Schuth, Nils; Gehring, H.; Horn, Bettina; Holze, Patrick; Kositzki, Ramona; Schrapers, Peer; Limberg, Christian; Haumann, Michael

Five biomimetic mono- or dinuclear nickel complexes featuring Ni(I) or Ni(II) sites were studied by X-ray absorption and emission spectroscopy and DFT calculations. Ni K-edge XANES spectra and Kβ main and satellite emission ...

The binuclear nickel center in the A-cluster of acetyl-CoA synthase (ACS) and two biomimetic dinickel complexes studied by X-ray absorption and emission spectroscopy

Schrapers, Peer; Mebs, Stefan; Ilina, Y.; Warner, D. S.; Wörmann, C.; Schuth, Nils; Kositzki, Ramona; Dau, Holger; Limberg, Christian; Dobbek, Holger; Haumann, Michael

Acetyl-CoA synthase (ACS) is involved in the bacterial carbon oxide conversion pathway. The binuclear nickel sites in ACS enzyme and two biomimetic synthetic compounds containing a Ni(II)Ni(II) unit (1 and 2) were compared ...
