A family of nanosized {Cu 6 Ln 12 } clusters with a 'windmill'-like topology was prepared from the employment of 2,6-diacetylpyridine dioxime, in conjunction with bridging N 3 − , 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. The first octadecanuclear {Cu 6 Ln 12 } clusters with a 'windmill'-like topology have been prepared from a 'ligand blend' comprising a pyridyl dioxime chelate and azides.
