Keywords: Iron carbonyl complexes, weakly coordinating anions



Research topics


Introduction & Motivation

The synthesis and stabilization of reactive cations with the help of weakly coordinating anions has been in the focus of our research for a long time. We draw our inspirations from the gas phase since only there, truly naked ions can exist. In the condensed phase, ligands, counter ions and solvents are required.
In order to achieve ‘Pseudo gas-phase conditions’, weakly bound systems are necessary. To be precise, this means little to non-coordinating anions, weakly coordinating yet polar solvents as well as weakly bound ligands, such as gas molecules (CO, NO, N2) or electron poor arenes.
Our Research
Over the course of my PhD, we were able to discover two previously unknown substance classes: homoleptic carbonyl radical cations and homoleptic nitrosyl cations. We were also able to widely expand the library of heteroleptic carbonyl/nitrosyl cations, as only one example was known to literature to date.
