摘要：

The compound [Gd(CuL)2(H2O)4][NO3]3.2H2O [H-2L = N,N'-bis(3-amino-2,2-dimethylpropyl)oxamide] was prepared and characterised by means of structural and magnetic measurements. The crystals are monoclinic, space group P2(1)/c, with a = 11.358(5), b = 16.932(4), c = 23.625(2) angstrom, beta = 103.47(3)degrees, and Z = 4. The structural unit consists of a trinuclear tripositive cation, three nitrate anions and two lattice water molecules. The central gadolinium and terminal copper metal ions are ferromagnetically coupled, J = -0.77 cm-1, while an antiferromagnetic coupling was detected between the terminal copper metal ions, J = 0.42 cm-1.
