Abstract

Four 52-metal-ion 3d-4f cluster complexes featuring a common core of Ln ₄₂M ₁₀ (Ln = Gd ³⁺, Dy ³⁺; M = Co ^2+/3+, Ni ²⁺) were obtained through self-assembly of the metal ions templated by mixed anions (ClO ₄ ^- and CO ₃ ^2-). Magnetic studies revealed that the Gd ₄₂Co ₁₀ and Gd ₄₂Ni ₁₀ clusters exhibit the largest magnetocaloric effect (MCE) among any known 3d-4f complexes. Replacement of Gd ³⁺ ions with anisotropic Dy ³⁺ ions caused significant changes in the magnetic behavior of the clusters; both Dy ₄₂Co ₁₀ and Dy ₄₂Ni ₁₀ displayed slow relaxation of the magnetization.
