Abstract
A series of mononuclear salen type copper(II) complexes, [CuLn] (n = 1–4), and their corresponding tetrahydrosalen complexes, [CuH2Ln] (n = 1,2) were prepared by the reaction of the N2O2 ligands with Cu(II) ion in ethanol, where H2L1 = N,N-bis(3,5-di-tert-butylsalicylidene)-2,2-dimethyle-1,3-diaminopropan, H2L2 = N,N-bis(3,5-di-tert-butylsalicylidene)-1,2-diaminopropane, H2L3 = N,N-bis(4-methoxysalicylidene)-2,2-dimethyle-1,3-diaminopropan; H2L4 = N,N-bis(4-methoxysalicylidene)-1,2-diaminopropane, H2[H2L1] = N,N-bis(2-hydroxyl-3,5-di-tert-butylphenyl)-2,2-dimethyle-1,3-diaminopropan and H2[H2L2] = N,N-bis(2-hydroxyl-3,5-di-tert-butylphenyl)-1,2-diaminopropane. The prepared ligands and complexes were characterized by the combination of IR, UV-Vis, NMR (as far as possible), elemental and thermal analyses. All prepared compounds were also evaluated for their antibacterial (Escherichia coli and Staphylococcus aureus) and antifungal (Candida albicans) activities by the disc diffusion method. The compounds were found have no remarkable antimicrobial activities.
