摘要：
A new family of {Cu(4)Ln(2)} (Ln = Gd, Tb and Dy) complexes bearing the gem-diol form of di-2-pyridyl ketone [(py)(2)CO] ligand is reported. Magnetic studies reveal the presence of predominant ferromagnetic exchange interactions between the metal ions. As a result, the hexanuclear compounds exhibit singlemolecule magnetism behavior and large magnetic entropy changes, depending on the 4f-metal ion present.
