Abstract
Three mononuclear cobalt and copper complexes, [Co(HL1)2]·[Co(L1)2] (1), [Cu(HL2)2] (2), and [CoL2(HL2)]2 (3), where HL1 and HL2 are the monoanionic form of 2-ethoxy-6-[(2-hydroxyethylimino)methyl]phenol (H2L1) and 4-bromo-2-[(2-hydroxyethylimino)methyl]phenol (H2L2), and L1 and L2 are the dianionic form of H2L1 and H2L2, have been synthesized and characterized by elemental analysis, FT-IR spectra, and single-crystal X-ray determination. The Co atoms in (1) and (3) are in octahedral coordination, and the Cu atom in (2) is in square planar coordination. The preliminary antibacterial activity of the complexes on the bacteria S. aureus, E. coli, P. aeruginosa, and S. typhi was evaluated.
