Redox-inactive metal ions modulate the reactivity and oxygen release of mononuclear non-haem iron(III)–peroxo complexes
Nature Chemistry. doi:10.1038/nchem.2055 Authors: Suhee Bang, Yong-Min Lee, Seungwoo Hong, Kyung-Bin Cho, Yusuke Nishida, Mi Sook Seo, Ritimukta Sarangi, Shunichi Fukuzumi & Wonwoo Nam Non-haem iron(III)-peroxo complexes that bind redox-inactive metal ions are synthesized to investigate the role of the Ca2+ ion in the oxidation of water to dioxygen in Photosystem II. The electrochemical properties and reactions of these compounds with an electron donor and an acceptor are found to be markedly dependent on the Lewis acidity of redox-inactive metal ions. |
