Abstract

Three isostructural 3d–4f polynuclear clusters {(Ln^III₆Co^II₆)(C8A)₃} (Ln = Y (CIAC-248), Eu (CIAC-249), Dy (CIAC-250); C8A = p-tert-butylcalix[8]arene) were synthesized under solvothermal conditions. These three compounds feature some tripod-like entities in which three Ln₂-C8A secondary building units acting as the legs bolster a [Co₆] hexagon. Magnetic study indicated that the complex {(Eu^III₆Co^II₆)(C8A)₃} (CIAC-249) exhibits spin glass behaviour at ≈9 K, and the complex {(Dy^III₆Co^II₆)(C8A)₃} (CIAC-250) shows slow relaxation of magnetization.
