摘要：
One novel complex [Co(p-MBA)2(2,2′-bipy)(H 2O)](H20) has been synthesized by the reaction of p-methylbenzoic acid with 2,2′-bipyridine in the solvent mixture of water and methanol. It crystallizes in triclinic, space group P1̄ with a = 0.70479(14), b = 1.1211(2), c = 1.6718(3) nm, α = 103.806(3), β= 90.795(3), γ = 104.207(3)°, V= 1.2399(4) nm3, Mr = 512.41, Dc= 1.373 g/cm3, Z = 2, F(000) = 532, μ = 0.733 mm-1, R= 0.0432 and wR = 0.0957. The crystal structural analysis shows that the cobalt atom is coordinated with three oxygen atoms from two p-methylbenzoic acids and one water molecule and two nitrogen atoms from one 2,2′-bipyridine, forming a distorted square-pyramidal coordination geometry. The cyclic voltammetry behavior of the complex is also reported.

摘要：
A new nickel(II) coordination complex [Ni(phen)3]·(m- nitrobenzoic acid)2-(H2O) was synthesized by self-assembly of m-nitrobenzoic acid, 1,10-phenanthroline and nickelous Perchlorate. It crystallizes in the monoclinic system, space group C2/c, with a = 2.4596(6), b = 1.2124(3), c = 1.9824(5) nm, β = 97.088(5)°, V = 5.866(3) nm 3, Dc = 1.474 g/cm3, Z = 4, Mr = 1301.82, μ(MoKα) = 0.417 mm-1 F(000) = 2688, R - 0.0493 and wR = 0.1025. Structural determination indicates that the nickel(II) ion is coordinated with six nitrogen atoms from three phens, giving a distorted octahedral coordination geometry. The cyclic voltametric analysis shows that the electron transfer in the electrode reaction is irreversible.
