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

Abstract Three new copper(II) and cadmium(II) complexes, [Cu(L1)2] (1), [CuL2(N3)] (2), and [Cd(L3)2] (3), where L1 = 2-bromo-4-chloro-6-cyclohexylaminomethylphenolate, L2 = 2-bromo-4-chloro-6-[(2-morpholin-4-ylethylimino)methyl]phenolate, and L3 = 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 <italic>B. subtilis</italic>, <italic>S. aureus</italic> and <italic>E. coli</italic>. [ABSTRACT FROM AUTHOR]
