文摘

A series of mixed metal 3d–4f gridlike structures, [Dy₄(H₂L′)₄Zn₄(SCN)₄] (1) and [Dy₄(H₂L′)₄M_x(SCN)₈] (M_x = Co₃ (2); M_x = Cu₅ (3)), showing Chinese hieroglyph like [2 × 2], [3 × 2], and [3 × 3] matrixes, were assembled and magnetically characterized. Remarkably, the empty cage constructed by the oblique organic ligands and SCN^– ions in complex 1 were filled with the large inorganic ions [Co₃(SCN)₄]²⁺ and [Cu₅(SCN)₄]⁶⁺ in complexes 2 and 3, respectively, forming the first [3 × 2] and [3 × 3] 3d–4f gridlike structures. Additionally, magnetic studies show that complex 1 exhibits field-induced SMM behavior and double magnetic relaxation, while complexes 2 and 3 display typical SMM behavior at zero applied field.
