A novel hexanuclear CuII4-GdIII2 cluster obtained from heterotrinuclear building blocks

The synthesis, structure and magnetic properties of the novel hexanuclear cluster [Cu4Gd2(H2L)4(NO3)4(H2O)3](NO3)2·5.5H2O·CH3COOH (1) were described. The compound was obtained by connecting heterotriniclear [CuII2GdIII] units with nitrato linkers. Magnetic analysis reveals ferromagnetic interactions between metal centers within the cluster with J value equal to JCu-Gd = 9.9(3) cm− 1.
