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.
