A new nickel(Ⅱ) complex Ni_2(L)_2(2,2?-bipy)2·5.5H_2 O with methy-bicycle[2.2.1]hept-5-ene-2,3-dicarboxylic acid(H2L) and 2,2?-bipyridine(2,2?-bipy) as ligands has been synthesized in the mixed solvent DMF and water(v:v = 5:2). It crystallizes in the triclinic space group P1 with a = 10.414(2), b = 12.884(3), c = 16.176(4) ?, α = 70.715(5), β = 80.599(5), γ = 77.383(6)o, V = 1989.4(8) ?3, Dc = 1.531 g/cm3, Z = 2, F(000) = 958, GOOF = 1.028, the final R = 0.0808 and w R = 0.2036. The crystal structure shows that the whole molecule consists of two independent dinuclear units, in which two nickel ions are bridged by two μ2-η1:η0 3-carboxylate groups of L2- anions. The coordination environment of Ni(Ⅱ) ion is Ni N_2O_3, giving a distorted square pyramidal geometry. The thermal stability and electrochemical properties of the complex were investigated.
