Elucidating transition metal clusters and complexes in cryo isolation — •Gereon Niedner-Schatteburg — Fachbereich Chemie and State Research Center OPTIMAS, TU Kaiserslautern, Germany

We utilize cryogenic ion trapping to record adsorption and activation kinetics, normal vibrations and magnetic moments of isolated transition metal (TM) clusters and their coordination complexes when held isolated void of environmental interferences. The characterization of such intrinsic properties in combination allows for far fetching conclusions on e.g. the morphologies and adsorbate induced reorganization of TM clusters, and the magnetostructural correlations within oligomeric TM complexes. We refer to published [1-7] as well as to most recent yet unpublished results [8-9].
