Abstract
A new Schiff base cobalt(III) complex with the formula [CoL1L2(N3)]·NO3 (L1 is 2-[1-(2-phenylaminoethylimino)ethyl]phenolate, L2 is N-phenylethane-1,2-diamine) is prepared and characterized by physicochemical methods and single crystal X-ray determination. The complex crystallizes in the triclinic system space group P-1, with a = 8.504(2) A, b = 14.973(3) A, c = 20.676(4) A, α = 100.021(3)°, β = 90.005(3)°, γ = 103.084(2)°, V = 2523.0(9) A3, Z = 4, R1 = 0.0732, and wR2 = 0.1182. Single crystal X-ray diffraction analysis reveals that the complex contains two mononuclear [CoL1L2(N3)]+ cations and two nitrate anions. The Co atom is six-coordinated in an octahedral geometry. The ligands and the cobalt(III) complex are screened in vitro for their antibacterial activity against Bacillus subtillis, Staphylococcus aureus, Escherichia coli, and Pseudomonas aereuguinosa.
