| Abstract: | The title complex has been synthesized by 4-methylbenzoic acid and 2,2'-bipyridine (bipy) in the mixed solvent of water and methanol. It crystallizes in the triclinic system, space group (P1-) with a = 0.7047(3), b = 1.1217(5), c = 1.6718(7) nm, α = 103.826(7), β = 90.772(6), γ = 104.195(6)°, C26H25CuN2O5.50, Mr = 517.02, V = 1.2404(9) nm3, Dc = 1.384 g/cm3, Z = 2, F(000) = 536, μ(MoKα= 0.921 mm-1, R = 0.0782 and wR = 0.2172. Structural analysis shows that the copper atom is coordinated with three oxygen atoms from two 4-methylbenzoic acids and one water molecule together with two nitrogen atoms from 2,2'-bipyridine, giving a distorted square-pyramid coordination geometry. The cyclic voltametric behavior of the complex has also been described. |
