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) nm^3, Dc = 1.384 g/cm^3, 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...
