Abstract

Two unprecedented wheel-shaped nanoscale clusters {Co^II₁₆Ln^III₂₄} (Ln = Dy and Gd), with a diameter and a thickness of 3.0 nm and 2.0 nm, respectively, were obtained from the self-assembly of Co(NO₃)₂, Ln(NO₃)₃ and a pyridyl-functionalized β-diketone ligand. Notably, the gadolinium species exhibited a relatively large magnetocaloric effect.
