Abstract

A family of nanosized {Cu₆Ln₁₂} clusters with a ‘windmill’-like topology was prepared from the employment of 2,6-diacetylpyridine dioxime, in conjunction with bridging N₃⁻, in 3d/4f-metal chemistry; the octadecanuclear compounds exhibit single-molecule magnetism behavior and large magnetic entropy changes, depending on the 4f-metal ion present.
