Copper(II) complexes of mono-condensed N,O-donor Schiff base ligands: Synthesis, crystal structures, and antibacterial activity

Аннотация

Two new copper(II) complexes, [Cu(L¹)₂] (I) and [Cu(L²)₂] (II), where L¹ = 2-bromo-4-chloro- 6-(isopropyliminomethyl)phenolate and L² = 2-bromo-4-chloro-6-[(2-hydroxyethylimino)methyl]phenolate, have been prepared and structurally characterized by X-ray crystallography (CIF files CCDC nos. 1445936 (I) and 1445935 (II)). In both complexes, the Cu atoms are coordinated by two phenolate oxygen and two imino nitrogen, giving square planar geometry. The complexes have been tested on various strains of bacteria to study their antibacterial effects.
