Abstract

We report the luminescence and magnetic properties of the mononuclear Dy(III) complex [DyTp₂Acac] (Tp = tris-pyrazolylborohydride and Acac = 2,4-pentanedionate). This complex displays peculiar slow magnetisation dynamics at low temperature in the absence of a static field, which we managed to interpret using its resolved luminescence spectrum and ab initio calculations.
