Chemistry of the Elements Technetium and Rhenium
|
|
The coordination chemistry and organometallic chemistry of technetium and rhenium was in the focus of our research for many years. This involved studies with the long-lived isotope 99Tc as well as with the short-lived nuclear isomer 99mTc.Many of our recent studies, particularly those with bulky terphenylisocyanides, were done in close collaboration with the group of Prof. Joshua Figueroa, University of California San Diego. |
