Abstract

The hydrolysis of Ln(ClO₄)₃ in the presence of acetate leads to the assembly of the three largest known lanthanide-exclusive cluster complexes, [Nd₁₀₄(ClO₄)₆(CH₃COO)₆₀(μ₃-OH)₁₆₈(μ₄-O)₃₀(H₂O)₁₁₂]·(ClO₄)₁₈·(CH₃CH₂OH)₈·xH₂O (1, x ∼ 158) and [Ln₁₀₄(ClO₄)₆(CH₃COO)₅₆(μ₃-OH)₁₆₈(μ₄-O)₃₀(H₂O)₁₁₂]·(ClO₄)₂₂·(CH₃CH₂OH)₂·xH₂O (2, Ln = Nd; 3, Ln = Gd; x ≈ 140). The structure of the common 104-lanthanide core, abbreviated as Ln₈@Ln₄₈@Ln₂₄@Ln₂₄, features a four-shell arrangement of the metal atoms contained in an innermost cube (a Platonic solid) and, moving outward, three Archimedean solids: a truncated cuboctahedron, a truncated octahedron, and a rhombicuboctahedron. The magnetic entropy change of δS_m = 46.9 J kg^-1 K^-1 at 2 K for δH = 7 T in the case of the Gd₁₀₄ cluster is the largest among previously known lanthanide-exclusive cluster compounds.
