Copper(II) and cadmium(II) complexes of mono-condensed N,O- or N,N,O-Donor ligands: synthesis, crystal structures, and antibacterial activity

Three new copper(II) and cadmium(II) complexes, [Cu(L-1)(2)] (1), [CuL2(N-3)] (2), and [Cd(L-3)(2)] (3), where L-1 = 2-bromo-4-chloro-6-cyclohexylaminomethylphenolate, L-2 = 2-bromo-4-chloro-6-[(2-morpholin-4-ylethylimino)methyl]phenolate, and L-3 = 2-bromo-4-chloro-6-[(3-morpholin-4-ylpropylimino)methyl]phenolate, have been prepared and structurally characterized by X-ray crystallography. The Cu atom in complex 1 is in tetrahedrally distorted square planar geometry. The Cu atom in complex 2 is in square planar geometry. The Cd atom in complex 3 is in octahedral geometry. The complexes exhibited effective activities against B. subtilis, S. aureus and E. coli.
