Abstract

We report the synthesis, photoluminescence and magnetic properties of two octahedral dysprosium complexes [DyR₂(py)₄][BPh₄]·2py (1) and [DyR₂(THF)₄][BPh₄] (2) (R = carbazolyl, py = pyridine, THF = tetrahydrofuran) exhibiting a quasi linear N–Dy–N angle in the axial direction, suitable for providing a coordination environment allowing the zero-field slow relaxation of magnetization.
