The synthesis of a 3d-4f polynuclear metal cluster under microwave irradiation: crystal structure and magnetic property of [La(3)Ni(6)(IDA)(6)(OH)(6)(H(2)O)(12)].3NO(3).15H(2)O (IDA = iminodiacetate).
A cage-shaped 3d-4f heterometallic ferromagnetic cluster, consisting of six Ni(ii) and three La(iii) ions, was synthesized by microwave irradiation. The magnetic susceptibilities of the cluster were fitted with the help of the program MAGPACK, revealing that the magnetic exchange in the cluster is closely related to the coordination mode and spatial distribution between the metal ions.
