Abstract

Three distorted tetrahedral Dy(iii) aryloxide complexes, [Na(THF) ₆][Dy(OAr ^Ad2tBu) ₂Cl ₂] (1) (OAr ^Ad2tBu= OC ₆H ₂Adamantyl ₂-2,6- ^tBu-4) and [Na(THF) ₆][Dy(OMes*) ₃X] (X = Cl, 2; BH ₄, 3), (OMes* = OC ₆H ₂ ^tBu ₃-2,4,6) exhibit easy axis magnetic anisotropy and slow magnetic relaxation at zero field, with relaxation rates 1 < 2 < 3.
