摘要
A new binuclear complex [Ni2（2,2＇-bpy）2（C8H3NO6）2（H2O）4] 1 （2,2＇-bpy = 2,2＇- bipyridine, C8H3NO6 = 4-nitrophthalate） has been synthesized by a hydrothermal reaction and characterized by X-ray single-crystal diffraction analysis. The complex crystallizes in triclinic, space group P1 with a = 7.206（2）, b = 10.337（4）, c = 12.480（4） , α = 89.887（11）, β = 77.033（9）, γ = 78.349（6）o, V = 886.3（5） 3, Z = 1, C36H30Ni2N6O16, Mr = 920.08, Dc = 1.724 g cm-3, F（000） = 472, μ = 1.152 mm-1, the final R = 0.0458 and wR = 0.1163 for 3372 observed reflections with I 2σ（Ⅰ）. The two Ni（Ⅱ） ions are bridged by two 4-nitrophthalates both in a bis-monodentate mode. Magnetic measurements reveal that the intramolecular exchange couplings in the dimer are ferromagnetic with 2J/k = 2.32 K, D =-1.44 K and g = 2.18.
