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