A family of ‘windmill’-like {Cu6Ln12} complexes exhibiting single-molecule magnetism behavior and large magnetic entropy changes

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.
