A comparative study of magnetization dynamics in dinuclear dysprosium complexes featuring bridging chloride or trifluoromethanesulfonate ligands.

We utilized a rigid ligand platform PyCp (PyCp = [2,6-(CHCH)CHN]) to isolate dinuclear Dy complexes [(PyCp)Dy-(μ-OSOCF)] (1) and [(PyCp)Dy-(μ-Cl)] (3) as well as the mononuclear complex (PyCp)Dy(OSOCF)(thf) (2). Compounds 1 and 2 are the first examples of organometallic Dy complexes featuring triflate binding. The isolation of compounds 1 and 3 allows us to comparatively evaluate the effects of the bridging anions on the magnetization dynamics of the dinuclear systems.
