Tenth paper from a Short-Term Scientific Mission (STSM) (July 28, 2016)
In this work the groups of Prof. Matthias Driess, Dr. A. Jalila Simaan, and Prof. Kallol Ray, demonstrate the systematic tuning of the electrophilicity/nucleophilicity of the oxygen atoms of a series of novel heterobimetallic [Ni(μ-O)2Cu]2+ cores by controlling the electron donation from the ancillary ligands. This study underlines the significance of subtle electronic changes in the physical and chemical properties of the biologically relevant heterobimetallic metal-dioxygen intermediates.
EPR, resonance Raman and reactivity studies were performed in the group of Prof. Kallol Ray and in collaboration with the cluster of excellence, UniCat, in the framework of two STSMs by Maria-Chrysanthi Kafentzi who is a PhD student of Dr. A. Jalila Simaan ((STSM-CM1305-28897 and STSM-CM1305-32182). This work was recently published in Dalton Transactions as an Open Access Article.
