A unique rearrangement reaction is presented for borate containing mesoionic carbenes. The corresponding CoII complexes display spin states, coordination geeometries and reactivities that are controlled through aogstic interactions on the secondary coordination sphere. A comprehensive NMR spectroscopic, crystallographic, EPR spectroscopic and theoretical study is presented on the ligands and the metal complexes.
